drm/i915/dmc: Set DMC_EVT_CTL_ENABLE for disabled event handlers as well

DMC_EVT_CTL_ENABLE cannot be cleared once set. So currently
any event we never enable will have DMC_EVT_CTL_ENABLE cleared,
whereas any event which has been enabled even once will have
DMC_EVT_CTL_ENABLE set. For that reason assert_dmc_loaded() has
a special case to ignore any mismatches in DMC_EVT_CTL_ENABLE.

Eliminate the special case by always configuring DMC_EVT_CTL_ENABLE
based on the original firmware event definition. Now all
event handlers will have DMC_EVT_CTL_ENABLE set, whether or
not the event has been enabled in the past.

All disabled event handlers will still have the event type set
to DMC_EVENT_FALSE so they will not actually trigger despite
DMC_EVT_CTL_ENABLE being set.
