spi: rzv2h-rspi: add support for variable transfer clock
The Renesas RZ/T2H (R9A09G077) and RZ/N2H (R9A09G087) SoCs have a more
complicated clocking setup for the SPI transfer clock than RZ/V2H, as
the clock from which it is generated supports multiple dividers.
To prepare for adding support for these SoCs, do the following changes.
Use the minimum frequency of SPI clock to calculate the SPI
controller's min_speed_hz, and the maximum frequency to calculate
max_speed_hz.
Apply the clock rate found by the .find_tclk_rate() to the found clock.
