The bitfield is the same for both so there is no functional change. This is just a cosmetic change to use the right bitfield macro.

The current implementation incorrectly updates DOMAIN11_PG_CONFIG with DOMAIN9_POWER_FORCEON, which is not the intended behavior. This patch corrects the power gating configuration by updating DOMAIN11_PG_CONFIG with DOMAIN11_POWER_FORCEON, preventing potential issues related to power management.
