rockbox: add a crc32 reverse polynomial function
This uses the reverse of the polynomial used by the current crc_32
function. The code for this was derived from the implementation used
by tinf. This version is space optimized and should be a good way to
reduce code duplication in other parts of rockbox that use the same
crc32 algorithm. This is mainly of use in areas where DEFLATE is in
use.
