drm/amd/display: Split DMUB cmd type into type/subtype
[Why]
Commands will be considered a stable ABI between driver and firmware.
Commands are also split between DC commands, DAL feature commands,
and VBIOS commands.
Commands are currently not designated to a specific ID and the enum
does not provide a stable ABI.
We currently group all of these into a single command type of 8-bits.
With the stable ABI consideration in mind it's not unreasonable to
run out of command IDs.
For cleaner separation and versioning split the commands into a main
type and a subtype.
[How]
For commands where performance matters (like reg sequences) these
are still considered main commands.
Sub commands will be split by ownership/feature.
Update existing command sequences to reflect new changes.
