mobile/gsm48_rr.c: set audio mode according to configuration 

In the prevoius change a new configuration option was introduced
as a part of new 'audio' node - 'io-target'. This change makes it
to take an effect, instructing the L1 to use one of the following
possible TCH frame I/O targets:

  - gapk - build-in (WIP) GAPK-based audio back-end (default);
  - hardware - L1 hardware (e.g. Calypso DSP);
  - socket - External MNCC application (e.g. LCR).
