[Intel-gfx] [PATCH 05/12] drm/i915: Do a bit of cleanup in the sprite code

[ville.syrjala at linux.intel.com]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

Move the variable initialization to where the variables are declared,
and kill a pointless to_intel_crtc() cast when we already have the
casted pointer.
