[PATCH] ASoC: fix snd_soc_jack_add_gpiods stub

[Arnd Bergmann <arnd@arndb.de>]

f025d3b9c64e1 ("ASoC: jack: Add support for GPIO descriptor defined jack
pins") added this new interface, but the stub function provided for
non-gpiolib builds was defined in the header file as a global function,
leading to lots of "multiple definition of `snd_soc_jack_add_gpiods'"
warnings.

This adds the obvious "static inline" annotation.
