We already support the VisionFive 2 and the Milk-V Mars board by
patching the VisionFive 2 device tree. With this patch the same
is done for the Milk-V Mars CM.

v2:
rename spl_fdt_fixup_marc() to spl_fdt_fixup_mars_cm()
rename device-trees for Mars CM and Mars CM Lite
change model and compatible properties
