commit 3c3ce77c9dab7f9628a9a96e881d0afb50ed74a6 upstream.

Document the RZ/V2M SoC bindings.
The RZ/V2M SoC is a little different to the R-Car implementations.
A few DRD related registers and bits have moved, there is a separate
interrupt for DRD, an additional clock for register access and reset
lines for DRD and USBP.
