mobile: set TRAFFIC.{ind,req} mode during call establishment

Now that we support data (CSD) calls in addition to voice calls,
we can no longer initialize the TRAFFIC.{ind,req} routing mode
in gsm48_rr_init().  We need to apply the appropriate TCH routing
mode *during call establishment* based on its type and the
configured I/O handler type.

After this patch, one can have the following configuration:

tch-voice
 io-handler l1phy
tch-data
 io-handler unix-sock
 io-tch-format ti

so that the io-handler setting for voice would not affect data calls.
Before this patch, the L1 PHY (specifically, Calypso firmware) would
not route TRAFFIC.{ind,req} during data calls at all.

Thanks to this patch, it's also no longer required to restart the
mobile application after changing voice or data I/O handler.
