Add support for the power controllers found in the MediaTek MT8196
Chromebook SoC.
This chip has three power controllers, two of which located in the
SCP subsystems (where one can be directly controlled and the other
can be controlled only through the HW Voter IP), and one located
in the Multimedia HFRP subsystem, controllable only through the HW
Voter IP.

Allow specifying access-controllers in the main power controller
node and deprecate the old mediatek,infracfg, mediatek,infracfg-nao
and mediatek,smi properties located in the children.
This is done in order to both simplify the power controller
nodes and in preparation for adding support for new generation
SoCs like MT8196/MT6991 and other variants, which will need
to set protection on new busses.

The MT8188 SoC has a more in-depth power-domain tree, and the
CHECK_DTBS=y check could fail because the current MediaTek power
dt-binding is insufficient to cover its CAM_SUBA and CAM_SUBB
sub-domains.
Add one more nested power-domain layer to pass the check.

The correct syntax for JSON pointers begins with a '/' after the '#'.
Without a '/', the string should be interpreted as a subschema
identifier. The jsonschema module currently doesn't handle subschema
identifiers and incorrectly allows JSON pointers to begin without a '/'.
Let's fix this before it becomes a problem when jsonschema module is
fixed.
