[PATCH v3 07/10] rockchip: rk3588: Sync sdmmc node from linux-next

[Jonas Karlman]

Sync the sdmmc node from linux-next, include required nodes in SPL and
imply Kconfig options required for functional sdmmc clk in SPL and
U-Boot proper.

This make it possible for both SPL and U-Boot proper to configure sdmmc
clocks. In SPL, before TF-A is loaded, scru regs is configured, in
U-Boot proper a SCMI message is sent to TF-A.
