Add power dt-bindings of MT8183 and introduces "BASIC" and
"SUBSYS" clock types in binding document.
The "BASIC" type is compatible to the original power control with
clock name [a-z]+[0-9]*, e.g. mm, vpu1.
The "SUBSYS" type is used for bus protection control with clock
name [a-z]+-[0-9]+, e.g. isp-0, cam-1.
