drm/i915/pmu: Drop redundant IS_VALLEYVIEW check in __get_rc6()

Because VLV_GT_RENDER_RC6 == GEN6_GT_GFX_RC6, the IS_VALLEYVIEW() check is
not needed. Neither is the check present in other code paths which call
intel_rc6_residency_ns() (in functions gen6_drpc(), rc6_residency() and
rc6_residency_ms_show()).

v2: Elimintate VLV_GT_RENDER_RC6 #define (Jani)
