drm/i915/skl: Enabling PSR2 SU with frame sync

We make use of HW tracking for Selective update region and enable frame sync on
sink. We use hardware's hardcoded data values for frame sync and GTC.

v2: Add 3200x2000 resolution restriction with PSR2, move psr2_support to i915_psr
struct, add aux_frame_sync to independently control aux frame sync, rename the
TP2 TIME macro for 2500us (Rodrigo, Siva)
v3: Moving the resolution restriction to intel_psr_enable so that we check it
only once(Durga)
