drm/cirrus: Compute blit destination offset in single location

Browse Source 
The calculation for the scanout-buffer blit offset is independent
from the color format. In the one case where the current code uses
fb->pitches[0] instead of cirrus->pitch, their values are identical.
Hence merge all into a single line.
