(no changes since v7)

Changes in v7:
- Fix GPU ID in commit message

Changes in v6:
- Context conflicts, reflow the code.
- Use ARRAY_SIZE for power domains too.

Changes in v5:
- Change power domain name from 2d to core2.

Changes in v4:
- Add power domain names.

Changes in v3:
- Match mt8183-mali instead of bifrost, as we require special
handling for the 2 regulators and 3 power domains.
