Lauri Kasanen ce92ee4b4f swscale/ppc: VSX-optimize non-full-chroma yuv2rgb_2 
./ffmpeg -f lavfi -i yuvtestsrc=duration=1:size=1200x1440 -sws_flags fast_bilinear \
        -s 1200x720 -f null -vframes 100 -pix_fmt $i -nostats \
        -cpuflags 0 -v error -

32-bit mul, power8 only.

~2x speedup:

rgb24
  24431 UNITS in yuv2packed2,   16384 runs,      0 skips
  13783 UNITS in yuv2packed2,   16383 runs,      1 skips

  13124 UNITS in yuv2packed2,   16384 runs,      0 skips

This is a low speedup, but the x86 mmx version also gets only ~2x. The mmx version
is also heavily inaccurate, while the vsx version has high accuracy.
