Rematrixing supports up to 64 channels. However, there is only a limited number of channel layouts defined. Since the in/out channel count is currently obtained from the channel layout, for undefined layouts (e.g. for 9, 10, 11 channels etc.) the rematrixing fails.

This patch changes rematrix init methods to use in (used) and out channel count directly instead of computing it from channel layout.

GCC requires the argument to vec_splat_u32 to be a literal.  The easiest
way to accomplish this is to change 'shift' to be const in scale (as it
is in the transform routine above), and convert both routines to be
inline.  This way, GCC can coerce the values to literals.

Tested on a 970 (Apple G5) and POWER9 (Talos II); passed fate and played
a clip of Big Buck Bunny correctly.
