[igt-dev] [PATCH i-g-t v3 2/2] tests/i915_pm_dc: psr required only for dc*-psr tests

[Anshuman Gupta]

DPMS igt tests were skipping for non-psr panels due to
psr_sink_support sink check added to igt_fixture() at
commit <6cbe6af372a01be63121056679d540436ffd0b64>.
DPMS dc state igt test don't require psr_sink_support, as it
validates DC states with all display being DPMS off.
Removing the psr sink check from igt_fixture and adding
it only for dc*- psr tests.

v2:
- Adding psr sink check to dc3co and moving ahead it
  in dc5/6 psr tests. [Jose]
