[PATCH 07/17] drm/i915: Use the new __drm_atomic_helper_crtc_reset() helper.

[Maarten Lankhorst <maarten.lankhorst@linux.intel.com>]

i915 has its own hw readout and doesn't use the reset helpers directly.
Still it has 2 places where it initialises the crtc_state. Fix those
by calling __drm_atomic_helper_crtc_reset().
