Loic Poulain 16caf1fa37 usb: chipidea: Add dynamic pinctrl selection ...

Some hardware implementations require to configure pins differently
according to the USB role (host/device), this can be an update of the
pins routing or a simple GPIO value change.

This patch introduces new optional "host" and "device" pinctrls.
If these pinctrls are defined by the device, they are respectively
selected on host/device role start.

If a default pinctrl exist, it is restored on host/device role stop.
