Document RSPI IP found on the RZ/G3L SoC. The RSPI IP is compatible with
the RZ/V2H RSPI IP, but has 2 clocks compared to 3 on RZ/V2H.

So even after my objections here:
https://lore.kernel.org/all/9d08ddda-403e-458d-95e4-4e76915df85d@kernel.org/

this was not fixed and Renesas did not provide actual cross-patch review.

This is still probably wrong as pointed out by other patches by Renesas.
Also, you cannot have flexible names.
