usb: renesas_usbhs: Add support for RZ/T2H SoC

Add support for the Renesas RZ/T2H (r9a09g077) SoC by adding a compatible
string to the usbhs_of_match table. The USBHS controller on the RZ/T2H is
functionally similar to the one found on the RZ/G2L. While there are minor
differences in register fields (for example, the AWAIT[8:13] bits in
SYSCFG1 register), the current driver does not configure these, allowing
reuse of the existing usbhs_rzg2l_plat_info for the RZ/T2H.
