Subject: drivers: usb :fsl: Remove USB Errata checking code

Remove USB errata checking code from driver. Applicability of erratum
is retrieved by reading corresponding property in device tree.
This property is written during device tree fixup.

Besides, replace spaces with tabs to make code aligned.

Subject: usb: typec: Rationalize the API for the muxes

Since with accessory modes there is no need for additional
identification when requesting a handle to the mux, we can
replace the second parameter that is passed to the
typec_mux_get() function with a pointer to alternate mode
description structure, and simply passing NULL with
accessory modes.

This change means the naming of the mux device connections
can be updated. Alternate and Accessory Modes will both be
handled with muxes named "mode-switch", and the orientation
switches will be named "orientation-switch".

Future identification of the alternate modes will be later
done using device property "svid" of the mux.

Subject: usb: core: add option of only authorizing internal devices

On Chrome OS we want to use USBguard to potentially limit access to USB
devices based on policy. We however to do not want to wait for userspace to
come up before initializing fixed USB devices to not regress our boot
times.

This patch adds option to instruct the kernel to only authorize devices
connected to the internal ports. Previously we could either authorize
all or none (or, by default, we'd only authorize wired devices).

The behavior is controlled via usbcore.authorized_default command line
option.
