[0/4] Add USB support for RK3308 SoC

Message

The RK3308 SoC features integrated USB controllers and PHYs. The USB
controller is compatible with the usual RK3066 USB controller, the phy is
in general compatible with the inno-usb2 phy structure but is not quite
the same as any of the phys supported yet.
This patchset adds USB support for the RK3308 SoC to both the RK3308 dtsi
and Rockchip inno-usb2 phy driver.
I've tested this patchset on a Rock Pi S, works flawlessly with HS, FS and
LS devices.

Cheers,
Tobias
