cae35e2460 gpio: allow pins to be enabled/disabled
Some GPIO controllers allow individual pins to be detached
from the controller (i.e. the controller no longer affects
the pin output, or can read its state).

This adds the configuration bits to the API so this feature
can be used by apps.

03066f26d8 gpio: change inline functions to static inline
When compiling with optimization level 0 (-O0), the linker complains
about missing references to uart functions. This is due to compiler
treating this functions as extern, since -O0 disables function inlining,
as described in https://gcc.gnu.org/bugzilla/show_bug.cgi?id=49653

So change the declaration to static inline.
