During DPMS on/off cycle DC5 counter is incremented. v2: Rename the subtest with meaningful name. v3: Rebased. v4: Addressed review comments by removing leftover code cleanup(). v5: Addressed the review comment by removing redundant read_dc_counter() suggested by Imre. Listing actual change in patch set changelog to make review easier. v6: Three way patch applied, no functional change. v7: Disabling runtime suspend for the platfrom which support, DC9. rebased due to test name pm_dc changed to i915_pm_dc, aligning to other PM tests.
