drm/i915/gen9+: Remove redundant state check during power well toggling
Atm we enable/disable a power well only if it wasn't already enabled/disabled respectively. The only reason for this I can think of is to save the extra MMIO writes. Since the HW state matches the power well's usage counter most of the time the overhead due to these MMIOs is insignificant. Let's simplify the code by making the writes unconditional.
