This change supports limited multiple device modes by:
- At most 4 ports contains OTG/Device capability.
- One port run as device mode at a time.

When device mode is set/unset, VBUS override activity is done via
exported functions from padctl driver. Use phy_set_mode() instead.

Padctl driver will act as a central driver to receive USB role changes via
usb-role-switch. This is updated to corresponding host, device drivers.
Hence remove usb-role-switch from XUDC driver.

Lots of changes on dwc3 this time, most of them from Thinh fixing a
bunch of really old mishaps on the driver.
DWC2 got support for STM32MP15 and a couple RockChip SoCs while DWC3
learned about Amlogic A1 family.
Apart from these, we have a few spelling fixes and other minor
non-critical fixes all over the place.

platform_get_irq() will call dev_err() itself on failure,
so there is no need for the driver to also do this.
This is detected by coccinelle.

The USB role callback functions had a parameter pointing to
the parent device (struct device) of the switch. The
assumption was that the switch parent is always the
controller. Firstly, that may not be true in every case, and
secondly, it prevents us from supporting devices that supply
multiple muxes.
Changing the first parameter of usb_role_switch_set_t and
usb_role_switch_get_t from struct device to struct
usb_role_switch.
