drm/i915/psr: Use hw.adjusted mode when calculating io/fast wake times

Browse source 
Encoder compute config is changing hw.adjusted mode. Uapi.adjusted mode
doesn't get updated before psr compute config gets called. This causes io
and fast wake line calculation using adjusted mode containing values before
encoder adjustments. Fix this by using hw.adjusted mode instead of
uapi.adjusted mode.
