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.

kernel.h: split out mathematical helpers kernel.h is being used as a dump for all kinds of stuff for a long time. Here is the attempt to start cleaning it up by splitting out mathematical helpers. At the same time convert users in header and lib folder to use new header. Though for time being include new header back to kernel.h to avoid twisted indirected includes for existing users.
