Christophe GISQUET 272b252c01 rv40dsp: implement prescaled versions for biweight. 
Quite often, the original weights are multiple of 512. By prescaling them
by 1/512 when they are computed (once per frame), no intermediate shifting
is needed, and no prescaling on each call either.

The x86 code already used that trick.
