Commit Message

Add support for MT8183's G-57 Bifrost.

Signed-off-by: Nicolas Boichat <[e-mail]>
---

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.
