spi: dt-bindings: renesas,rzv2h-rspi: document RZ/T2H and RZ/N2H

Browse source

The Renesas RZ/T2H (R9A09G077) and RZ/N2H (R9A09G087) SoCs have four SPI
peripherals.

Compared to the previously supported RZ/V2H, these SoCs have a smaller
FIFO, no resets, and only two clocks: PCLKSPIn and PCLK. PCLKSPIn,
being the clock from which the SPI transfer clock is generated, is the
equivalent of the TCLK from V2H.

Document them, and use RZ/T2H as a fallback for RZ/N2H as the SPIs are
entirely compatible.
