This patch series adds new tests to validate Display C states.
DC states like DC5 and DC6 are validated during PSR entry/exit
and during DPMS on/off cycle.

Sending new revision of patch series after addressing review comments and
other relevant changes.

1. Changing the name of test from pm_dc to i915_pm_dc alinged to other PM tests.
2. Changing the DC5/6 counter check timeout from 1 sec to 3 sec,
   as in case of PSR  it requires more than 2 second to disable DC
   power wells after vblank event.
3. Changed the test name from tests/pm_dc to tests tests/i915/i915_pm_dc in
   name of individual patch.
