[PATCH v2] drm/i915/selftests: Increasing the sleep time for live_rc6_manual

[Sk Anirban]

From: Anirban Sk <sk.anirban at intel.com>

Sometimes gt_pm live_rc6_manual selftest fails due to no power being
measured for the rc6 disabled period. Therefore increasing the rc6 disable
period from 250ms to 1000ms to rule out such sporadic failure.
