stm32/usb: Add HOOK_USB_PM_CHANGE, called when USB is resumed/suspended
In particular, this will allow touchpad driver and keyboard matrix
scanning to be powered off/disabled when the USB interface is
disabled without setting the remote wake feature
(USB_REQ_FEATURE_DEVICE_REMOTE_WAKEUP), as events would be
ignored anyway.
BRANCH=none
BUG=b:72683995
TEST=With next CLs, touchpad and keyboard matrix scanning are disabled
when lid is closed.
