[PATCH v2 16/24] ASoC: rsnd: Add rsnd_adg_mod_get() for PM support

[John Madieu]

Add rsnd_adg_mod_get() to retrieve the ADG module handle.

This is preparation for system suspend/resume support, where the PM
callbacks need to access the ADG module to manage its clock and reset
state. Other modules (SSI, SRC, CTU, MIX, DVC) already have their
getters exported.

v2: Moved export part into a new patch (the next one)
