Hi All,

Add support for the xSPI (Extended SPI) Interface on Renesas RZ/T2H and
RZ/N2H SoCs. The xSPI IP on these SoCs is closely related to that found
on the RZ/G3E SoC with some register bit differences in the configuration
registers.

v1->v2:
- Add RB tag from Rob for the dt-bindings patch.
- Add RB tag from Wolfram for the rpc-if duplicate device name patch.
- Added xspi_info_r9a09g077 for RZ/T2H with type XSPI_RZ_T2H instead
of reusing xspi_info_r9a09g047 with type XSPI_RZ_G3E, to allow for
better differentiation in the future if needed.

v1: https://lore.kernel.org/all/20260310212927.3372410-1-prabhakar.mahadev-lad.rj@xxxxxxxxxxxxxx/

Note, patches apply on to of next-20260326

Cheers,
Prabhakar
