From: Jyoti Yadav <jyoti.r.yadav@intel.com>

This patch add subtest to check DC6 entry on PSR for the supported
platforms.

v2: Rename the subtest with more meaningful name.
v3: Rebased.
v4: Rebased, to fix compilation error in psr_enable().
Addressed review comment by fixing typo in comment description
of DC6 PSR subtest.
v5: Addressed the review comment by removing redundant read_dc_counter(),
clubbed cleanup() function in test_dc_state_psr() suggested by Imre.
Listing actual change in patch set changelog to make review easier.
v6: Rebased due to test name pm_dc changed to i915_pm_dc, aligning to
other PM tests.
