41a4629621 drm/i915/psr: convert intel_psr.[ch] to struct intel_display 
Going forward, struct intel_display shall replace struct
drm_i915_private as the main display device data pointer type. Convert
intel_psr.[ch] to struct intel_display.

Some stragglers are left behind where needed.

value into intel_psr struct indicating whether Early Transport is enabled
or not and use it instead of psr2_su_region_et_valid for getting Early

04c09e4b87 drm/i915: Simplify PIPESRC_ERLY_TPT definition 
PIPESRC_ERLY_TPT is a pipe register, and it lives in the 0x70000 range.
so using _MMIO_TRANS2() for it is not really correct. Also since this
is a pipe register, and not present on CHV, the registers will be
equally spaced out, so we can use the simpler _MMIO_PIPE() instead
of _MMIO_PIPE2().
