[PATCH v3 1/3] drm/xe: Cleanup force wake registers bit definitions

- Remove unused bit definitions.
- Driver uses BIT(0) for waking/sleeping the domain and since the
registers are masked respective mask bit BIT(16) needs to be set. Use
defines for these bits and use them in domain initialization.
