Changes in v11: None Changes in v10: None Changes in v9: None Changes in v8: None 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.
Changes in v2: None
