Document support for the Expanded Serial Peripheral Interface (xSPI)
controller found on the Renesas RZ/V2H(P) (R9A09G057) and RZ/V2N
(R9A09G056) SoCs.
The xSPI hardware block on these SoCs is functionally identical to the
one on the RZ/G3E (R9A09G047) SoC. Therefore, the existing driver can be
reused without modification by using `renesas,r9a09g047-xspi` as a
fallback compatible.
