wm4 2123bff6fa vo_gl: remove support for nvidia register combiners (yuv=1) 
The register combiner color conversion is broken and seems to use a
slightly incorrect color matrix (the image looks gray-ish). Completely
remove all code related to nVidia register combiners.

Unless you have an ancient nVidia GPU, there's no reason to prefer register
combiners over fragment shaders. Users with ancient GPUs without fragment
shader support can just use -vo xv.

Passing yuv=1 (register combiners) as sub option will print a warning and
use yuv=2 (fragment shaders) instead.
