Booting from SDMMC is one of the fast and easy booting methods
for initial support of any SoC to upstream more features.
This patch is trying to add the sdmmc node for rk3588 and added
as u-boot specific node in -u-boot.dtsi as upstream Linux is not
supporting yet.
As soon as Linux supports it, a sync of the Linux device tree
would eventually drop this node.
Clock properties as added according to the rockchip mmc driver
but the actual definition might add scmi clocks into 0 and 1
indexes. This is due to scmi clock are not supporting in upstream
U-Boot. Properly addition of scmi clock would eventually follow
sdmmc clock definition of Linux once they upstreamed.

Rockchip SoCs typically use U-Boot TPL to initialize DRAM, then jumps
back to BootRom to load next stage, U-Boot SPL, into DRAM. BootRom then
jumps to U-Boot SPL to continue the normal boot flow.
However, there is no support to initialize DRAM on RK35xx SoCs using
U-Boot TPL and instead an external TPL binary must be used to generate a
bootable u-boot-rockchip.bin image.
Add CONFIG_ROCKCHIP_EXTERNAL_TPL to indicate that an external TPL should
be used. Build U-Boot with ROCKCHIP_TPL=/path/to/ddr.bin to generate a
bootable u-boot-rockchip.bin image for RK3568.
