[PATCH v6 01/25] drm/xe: Add member initialized_domains to xe_force_wake()

[Himal Prasad Ghimiray]

This field serves as a bitmask representing all initialized forcewake
domains on the GT.

While at it, fix the datatype for awake_domains since it can have
value different from enum xe_force_wake_domains.
