[RFC 7/8] drm/i915/vlv: Move active watermarks into intel_crtc->wm.active.vlv

[Chi Ding <chix.ding@intel.com>]

From: Maarten Lankhorst <maarten.lankhorst@linux.intel.com>

Previously the active watermarks is saved in intel_crtc->wm_state
This commit adds a new field "vlv" into intel_crtc->wm.active and save
the active watermarks in it to be consistent with what we do on other
platforms.
