drm/i915/dmc: Fixup TGL/ADL-S HRR event handler type

TGL/ADL-S DMC firmware incorrectly uses the undelayed vblank
trigger for the HRR event, when it should be using the delayed
vblank trigger.

Fixed DMC firmware was never relaesed and isntead the Windows
driver just fixes this up by hand. Follow suit.

Not that we actually enable the HRR event currently. But let's
fix up the event ID, just in case someone ever needs to enable
this.
