arm: dts: Add SD dts for the sc598 EZKIT

Browse Source 
The eMMC and SD card on the sc598 share pins, so they cannot be
used at the same time. Previously, this was managed with a patch applied
by the relevant build system, but patches are brittle and have to be
maintained. Instead, they have been replaced with two separate device trees
, one for eMMC and one for SD card, which inherit a shared base dtsi.
The build system can then select between the default device tree which
enabled eMMC or the other device tree which enables SD card support.
