dt-bindings: usb: renesas,usbhs: Add RZ/T2H and RZ/N2H support

Document the USBHS controller for the Renesas RZ/T2H (r9a09g077) and
RZ/N2H (r9a09g087) SoCs. While the USBHS block is similar to the one found
on the RZ/G2L SoC, it differs slightly in terms of interrupt configuration,
clock/reset requirements, and register bit definitions. Due to these
differences, a new compatible string `renesas,usbhs-r9a09g077` is
introduced for the RZ/T2H SoC.

The USBHS controller on the RZ/N2H (r9a09g087) SoC is identical to that on
the RZ/T2H, so it uses the `renesas,usbhs-r9a09g077` compatible string as
a fallback.
