These patches introduce the MediaTek MUSB controller driver.
The driver can be configured as Dual-Role Device (DRD),
Peripheral Only and Host Only modes. This has beed tested on
MT2701 with a variety of devices in host mode and with the
f_mass gadget driver in peripheral mode, plugging otg cables
in/out a lot of times in all possible imaginable plug orders.
changes in v5:
