[FFmpeg-cvslog] lsws/ppc/yuv2rgb_altivec: Replace vec_lvsl/vec_perm with vec_xl

lsws/ppc/yuv2rgb_altivec: Replace vec_lvsl/vec_perm with vec_xl
gcc 6.x and 7.x generate wrong code for little endian machines
for the vec_lvsl/vec_perm instruction combos in some cases.
The bug was fixed in version 8.x
If these instructions are replaced with vec_xl, the problem goes
away for all versions of the compilers.
Fixes ticket #7124.
