[MPlayer-dev-eng] another RGB ordering fix for altivec

[Alan Curry]

This time it's the unscaled 32-bit yuv2rgb conversions getting attention.
When these are put next to each other, it becomes clear that they can't both
be right:

  DEFCSP420_CVT (yuv2_bgra32, out_argb)
  DEFCSP420_CVT (yuv2_argb32, out_argb)

This fixes it. It also abolishes the "bgra32"-style function names. There's
already "ABGR" and "RGB32", which thanks to DOCS/tech/colorspaces.txt you can
at least find out what they are (although I think I'll never know *why*). How
many different names for the same thing do we need?

While I was in there, I also added the 2 missing 32-bit formats to the
switch().

Did this break anything? Is anyone in love with the /[argb]{4}32/ names?
