Replaced Taylor series calculation for (co)sine with a
look up table (LUT) for sine values.
Kernel has already a LUT for sin/cos at:
include/linux/fixp-arith.h
The best would be to either use it or improve its precision, if the one there
is not good enough.
I looked that one when made generator. It has poor precision and it uses
degrees not radians. But surely it is correct practice improve existing
than introduce new.
