USB-serial updates for v4.7-rc1
These updates fixes a number of issues where resources were not properly
released on probe errors. Included is also a fix for hardware
flow-control disable for cp210x.
Support for Moxa UPort 11x0 is added to the ti_usb_3410_5052 driver, and
included are also some general code clean ups.

The ohci-platform driver can control the clock, while usb-nop-xceiv
as the PHY can control the vbus regulator. So this JZ4740-specific

- UPort 1130I : 1 port RS-422/485 USB to Serial Hub with Isolation.
- UPort 1150 : 1 port RS-232/422/485 USB to Serial Hub.
- UPort 1150I : 1 port RS-232/422/485 USB to Serial Hub with Isolation.

Turns out the template and thus many drivers got the return value wrong:
0 means the fabrics driver needs to put a session reference, which no
driver except for the iSCSI target drivers did. Fortunately none of these
drivers supports explicit Node ACLs, so the bug was harmless.
Even without that only qla2xxx and iscsi every did real work in
shutdown_session, so get rid of the boilerplate code in all other
drivers.

Due to a missing upper bound, invalid minor numbers could be assigned to
ports. Such devices would later fail to register, but let's catch this
early as intended and avoid having devices with only a subset of their
ports registered (potentially the empty set).

The interface read URB is submitted in attach, but was only unlinked by
the driver at disconnect.
In case of a late probe error (e.g. due to failed minor allocation),
disconnect is never called and we would end up with active URBs for an
unbound interface. This in turn could lead to deallocated memory being
dereferenced in the completion callback.

been killed by usb-serial core on disconnect.

The interface instat and indat URBs were submitted in attach, but never
unlinked in release before deallocating the corresponding transfer
buffers.
In the case of a late probe error (e.g. due to failed minor allocation),
disconnect would not have been called before release, causing the
buffers to be freed while the URBs are still in use. We'd also end up
with active URBs for an unbound interface.

URBs and buffers allocated in attach for Epic devices would never be
deallocated in case of a later probe error (e.g. failure to allocate
minor numbers) as disconnect is then never called.
Fix by moving deallocation to release and making sure that the
URBs are first unlinked.

The firmware of R-Car USB 3.0 host controller will control the reset.
So, if the xhci driver doesn't do firmware downloading (e.g. kernel
configuration is CONFIG_USB_XHCI_PLATFORM=y and CONFIG_USB_XHCI_RCAR
is not set), the reset of USB 3.0 host controller doesn't work
correctly. Then, the host controller will cause long wait in
xhci_reset() because the CMD_RESET bit of op_regs->command is not
cleared for 10 seconds.
So, this patch modifies the Kconfig to enable both CONFIG_USB_XHCI_PLATFORM
and CONFIG_USB_XHCI_RCAR.

When a USB driver is bound to an interface (either through probing or
by claiming it) or is unbound from an interface, the USB core always
disables Link Power Management during the transition and then
re-enables it afterward. The reason is because the driver might want
to prevent hub-initiated link power transitions, in which case the HCD
would have to recalculate the various LPM parameters. This
recalculation takes place when LPM is re-enabled and the new
parameters are sent to the device and its parent hub.
However, if the driver does not want to prevent hub-initiated link
power transitions then none of this work is necessary. The parameters
don't need to be recalculated, and LPM doesn't need to be disabled and
re-enabled.
It turns out that disabling and enabling LPM can be time-consuming,
enough so that it interferes with user programs that want to claim and
release interfaces rapidly via usbfs. Since the usbfs kernel driver
doesn't set the disable_hub_initiated_lpm flag, we can speed things up
and get the user programs to work by leaving LPM alone whenever the
flag isn't set.
And while we're improving the way disable_hub_initiated_lpm gets used,
let's also fix its kerneldoc.

This reverts commit e3345db85068ddb937fc0ba40dfc39c293dad977, which
broke system resume for a large class of devices.
Devices that after having been reset during resume need to be rebound
due to a missing reset_resume callback, are now left in a suspended
state. This specifically broke resume of common USB-serial devices,
which are now unusable after system suspend (until disconnected and
reconnected) when USB persist is enabled.
During resume, usb_resume_interface will set the needs_binding flag for
such interfaces, but unlike system resume, run-time resume does not
honour it.

The debugging facilities in ehci-dbg.c follow an uneven pattern. Some

USB Type-C Connector System Software Interface (UCSI) is
specification that defines the registers and data structures
that can be used to control USB Type-C ports on a system.
UCSI is used on several Intel Broxton SoC based platforms.
Things that UCSI can be used to control include at least USB
Data Role swapping, Power Role swapping and controlling of
Alternate Modes on top of providing general details about
the port and the partners that are attached to it.
The initial purpose of the UCSI driver is to make sure USB
is in host mode on desktop and server systems that are USB
dual role capable, and provide UCSI interface.
The goal is to integrate the driver later to an USB Type-C
framework for Linux kernel, and at the same time add support
for more extensive USB Type-C port control that UCSI offers,
for example data role swapping, power role swapping,
Alternate Mode control etc.
The UCSI specification is public can be obtained from here:
