[v5,3/4] RFC: drm/panfrost: Add mt8183-mali compatible string

Commit Message

For testing only, the driver doesn't really work yet, AFAICT.

v5:
 - Change power domain name from 2d to core2.
v4:
 - Add power domain names.
v3:
 - Match mt8183-mali instead of bifrost, as we require special
   handling for the 2 regulators and 3 power domains.
