drm/i915/skl: Enabling PSR on Skylake
Mainly taking care of some register offsets, otherwise things are similar to
hsw. Also, programming ddi aux to use hardcoded values for psr data select.
v2: introduce EDP_PSR_AUX_BASE macro (Chris)
v3: Moving to HW tracking for SKL+ platforms, so activating source psr during
psr_enabling and then avoiding psr entries and exits for each frontbuffer
updates.
v4: Using SKL DDI AUX regs instead of changing PSR_AUX regs definition (Rodrigo)

[danvet: Drop the hunks to short-circuit sw tracking: We'd need to
push this down one level, and I don't fully trust the test coverage
yet to do so. So much prefer we pick a whitelist approach for the
cases we know work correctly.]
