Subject: [PATCH] regmap: provide dummy regmap_exit()

Fixes build error:

sound/soc/soc-core.c: In function 'snd_soc_component_exit_regmap':
sound/soc/soc-core.c:2644:2: error: implicit declaration of function 'regmap_exit' [-Werror=implicit-function-declaration]
  regmap_exit(component->regmap);

Due to the other regmap functions providing appropriate stubs when
!CONFIG_REGMAP, but this one is missing. Add it.
