dt-bindings: usb: renesas,usb3-peri: Document RZ/V2MA bindings

Document RZ/V2MA usb3-peri bindings. RZ/V2MA usb3-peri is identical
to one found on the RZ/V2M SoC. No driver changes are required as
generic compatible string "renesas,rzv2m-usb3-peri" will be used as
a fallback.

dt-bindings: usb: renesas,usb3-peri: Update reset, clock-name and interrupts properties

On RZ/V2M, USB3DRD module manages the drd_reset. Moreover, the interrupts
drd, gpi and bc are part of USB3DRD block. This patch removes
drd_reset and the interrupts drd, bc and gpi from usb3_peri bindings.
After this, there is only one reset and interrupts and therefore
removing reset-names and interrupt-names as well.

Whilst, Update the clock-name "aclk"->"axi" to make it consistent with
DRD and host blocks.

There is any harm in making such a change as, no users of
renesas,r9a09g011-usb3-peri yet in kernel release.

dt-bindings: usb: renesas, usb3-peri: Document RZ/V2M r9a09g011 support

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.

dt-bindings: usb: Use OF graph schema

Now that we have a graph schema, rework the USB related schemas to use
it. Mostly this is adding a reference to graph.yaml and dropping duplicate
parts from schemas.

dt-bindings: Fix incorrect 'reg' property sizes

The examples template is a 'simple-bus' with a size of 1 cell for
had between 2 and 4 cells which really only errors on I2C or SPI type
devices with a single cell.

The easiest fix in most cases is to change the 'reg' property to for 1 cell
address and size. In some cases with child devices having 2 cells, that
doesn't make sense so a bus node is needed.
