From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>
We have several places where we want to allocate a pristine
crtc state. Some of those currently call intel_crtc_state_reset()
to properly initialize all the non-zero defaults in the state, but
some places do not. Let's add intel_crtc_state_alloc() to do both
the alloc and the reset, and call that everywhere we need a fresh
crtc state.
