drm/i915/pps: Don't apply quirks/etc. to the VBT PPS delays if they haven't been initialized

Browse Source 
Skip QUIRK_INCREASE_T12_DELAY and the t11_t12 adjustment of the
VBT PPS delays if we've not yet initialized them. Will be important
later when the PPS delay init can happen before VBT parsing.
