GPIO fixes for the v3.17 series:

- Some documentation sync
- Resource leak in the bt8xx driver
- Again fix the way varargs are used to handle the
  optional flags on the gpiod_* accessors. Now hopefully
  nailed the entire problem.

gpio: move varargs hack outside #ifdef GPIOLIB

commit 39b2bbe3d715cf5013b5c48695ccdd25bd3bf120
"gpio: add flags argument to gpiod_get*() functions"
added a dynamic flags argument to all the GPIOD getter
functions, however this did not cover the stubs so
when people used gpiod stubs to compile out descriptor
code, compilation failed.

Solve this by:
- Also rename all the stub functions __gpiod_*
- Moving the vararg hack outside of #ifdef CONFIG_GPIOLIB
  so these will always be available.
