[PATCH 16/22] ASoC: rsnd: Export module getters for PM support

[John Madieu]

Export rsnd_adg_mod_get() and rsnd_ssiu_mod_get() to make them
accessible from core.c.

This is preparation for system suspend/resume support, where the PM
callbacks need to iterate over all modules to save and restore their
clock and reset state. Other modules (SSI, SRC, CTU, MIX, DVC) already
have their getters exported.
