Change the comptiable for support of multi-platform
Make compatible explicit
Add description for reg
Add description for source_cg
Add description for mediatek,latch-ck
Note that source_cg and mediatek,latch-ck are optional for some projects,
eg, MT2701 do not have source_cg, and MT2712 do not need
mediatek,latch-ck
