[PATCH v3 5/8] msm: gpiomux: Move public API to public header

[David Brown <davidb@codeaurora.org>]

The gpiomux.h header contains some SOC ifdefs.  However, the API that
is actually used by the GPIO driver only uses two functions that are
general.  Move these general definitions into a public header file.
