[PATCH 13/14] drm/i915/dsb: s/dsb/dsb_color_vblank/

[Ville Syrjala]

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

We'll soon utilize several DSBs during the commit. To that end
rename the current crtc_state->dsb to crtc_state->dsb_color_vblank
to better reflect its role (color managemnent stuff programmed during
vblank).
