[PATCH v3 03/28] drm/xe/pf: Convert control state to bitmap

[Michał Winiarski]

In upcoming changes, the number of states will increase as a result of
introducing SAVE and RESTORE states.
This means that using unsigned long as underlying storage won't work on
32-bit architectures, as we'll run out of bits.
Use bitmap instead.
