lib/math: move int_pow() from pwm_bl.c for wider use The integer exponentiation is used in few places and might be used in the future by other call sites. Move it to wider use.

lib: Move mathematic helpers to separate folder For better maintenance and expansion move the mathematic helpers to the separate folder. No functional change intended. Note, the int_sqrt() is not used as a part of lib, so, moved to regular obj.

lib/math: Add a `do_div' test module Implement a module for correctness and performance evaluation for the `do_div' function, often handled in an optimised manner by platform code. Use a somewhat randomly generated set of inputs that is supposed to be representative, using the same set of divisors twice, expressed as a constant and as a variable each, so as to verify the implementation for both cases should they be handled by different code execution paths. Reference results were produced with GNU bc. At the conclusion output the total execution time elapsed. Signed-off-by: Maciej W.
