[1/3] dt-bindings: spi: renesas,rspi: Document RZ/G2L SoC

Add RSPI binding documentation for Renesas RZ/G2L SoC.

RSPI block is identical to one found on RZ/A, so no driver changes are
required the fallback compatible string "renesas,rspi-rz" will be used
on RZ/G2L

Right, I completely missed that.

Please submit patches using subject lines reflecting the style for the
subsystem, this makes it easier for people to identify relevant patches.
Look at what existing commits in the area you're changing are doing and
make sure your subject lines visually resemble what they're doing.
There's no need to resubmit to fix this alone.

Hi Mark,

Thank you for the review.

My bad will update it to "spi: dt-bindings: renesas,rspi: Document
RZ/G2L SoC" and re-send a v2 along with the review commented by Geert.
