pinctrl: move generic functions to the pinctrl_ namespace

Browse source 
Since we want to use the former pinmux handles and mapping tables for
generic control involving both muxing and configuration we begin
refactoring by renaming them from pinmux_* to pinctrl_*.

ChangeLog v1->v2:
- Also rename the PINMUX_* macros in machine.h to PIN_ as indicated
  in the documentation so as to reflect the generic nature of these
  mapping entries from now on.
