By default, ina3221, as a hardware monitor, continuously measures
the inputs and generates corresponding data. However, for battery
powered devices, this mode might be power consuming.
The DT binding doc is updated with a new boolean type property to
allow changing the default operating mode from consuming mode to
single-shot mode, which will measure input on demand and then shut
down to save power.
So this patch implements the DT property accordingly.

Current code compares device name with name in i2c_device_id to decide
whether PMBUS_SKIP_STATUS_CHECK should be set in pmbus_platform_data,
which makes adding new devices with PMBUS_SKIP_STATUS_CHECK should also
modify code in pmbus_probe().
This patch adds pmbus_device_info to save pages and flags. Its pointer
is put in driver_data of i2c_device_id, which makes adding new device
more straightforward.

Fix tps53679_probe() by using dynamically allocated "pmbus_driver_info"
structure instead of static. Usage of static structures causes
overwritten of the field "vrm_version", in case the system is equipped
with several tps53679 devices with the different "vrm_version".
In such case the last probed device overwrites this field for all
others.

pci_map_rom/pci_get_rom_size() performs memory access in the ROM.
In case the Memory Space accesses were disabled, readw() is likely
to trigger a synchronous external abort on some platforms.
In case memory accesses were disabled, re-enable them before the
call and disable them back again just after.

PCI core handles save and restore of device state around reset, but
when using pci_set_power_state() we can unintentionally trigger a soft
reset of the device, where PCI core only restores the BAR state. If
we're using vfio-pci's idle D3 support to try to put devices into low
power when unused, this might trigger a reset when the device is woken
for use. Also power state management by the user, or within a guest,
can put the device into D3 power state with potentially limited
ability to restore the device if it should undergo a reset. The PCI
spec does not define the extent of a soft reset and many devices
reporting soft reset on D3->D0 transition do not undergo a PCI config
space reset. It's therefore assumed safe to unconditionally restore
the remainder of the state if the device indicates soft reset
support, even on a user initiated wakeup.
Implement a wrapper in vfio-pci to tag devices reporting PM reset
support, save their state on transitions into D3 and restore on
transitions back to D0.

The existed commit 6d8c50dcb029 ("socket: close race condition between sock_close()

that crypto module forgets to set the sk to NULL after af_alg_release.
