drm/i915: Introduce intel_crtc_state_alloc()

Browse source

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.

v2: s/kzalloc/kmalloc/ since we memset() anyway (José)
