Re-organize files by topic

Keil project not updated, I have no way to verify it.

Note, mw.c, drv_pwm.c and drv_system.c contain code for too many topics.
Later commits will relocate the code as appropriate.

Not even looked at utils yet.  'Utils' is a bad naming practice and is a
synonym for 'too lazy to find the right file/name'.
