spi: rzv2h-rspi: avoid recomputing transfer frequency
Renesas RZ/T2H (R9A09G077) and RZ/N2H (R9A09G087) SoCs have a more
complicated algorithm for calculating the optimal SPI transfer frequency
compared to RZ/V2H, as the clock from which the SPI frequency is
generated supports multiple dividers.
Cache the requested transfer frequency and skip calling
rzv2h_rspi_setup_clock() if it matches the last used one to prepare for
adding support for variable clock frequency handling.
