drm/i915/fbc: update the panel_replay dependency in fbc wa's

There are two panel_replay scenarios fbc wa need to be aware of,
panel replay with and without selective update capability.
Panel replay without selective update don't have any fbc wa.
So keep the fbc psr1 wa as it is.

The current fbc psr2 wa is mainly about selective fetch and we
need to apply the fbc wa if selective fetch is on - irrespective
of panel replay. Hence we can't exclude panel replay from the
fbc psr2 wa.

v1: keep panel_replay exclusion in PSR1 case (Jouni)
