Hi All,

This patch series adds support for SD/eMMC on Renesas RZ/G2L SoC and
enables this interfaces on Renesas RZ/G2L SMARC EVK.

All the patches have been cherry picked from v5.17 release.

Resending as I had missed a patch (0001) earlier, reset of the patches
havent been changed. And also for some reason patches didnt make into
patchwork.

Cheers,
Prabhakar
