ASoC: rt5677: add GPIO get_direction and enable standalone compilation

Browse Source 
Diogo Ivo <diogo.ivo@bootlin.com> says:

This small series fixes two issues in the RT5677 ASoC codec driver:

- Patch 1 adds the missing GPIO .get_direction() callback, allowing
  the direction of GPIO pins to be queried.

- Patch 2 makes the Kconfig option user-visible so the driver can be
  built standalone for example when using generic audio-graph-card
  bindings, which do not pull in specific codec drivers via select/imply.
