Andy Shevchenko 9f61589469 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.

Andy Shevchenko 2c64e9cb0b 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.
