Add dyn_pdch_init() in new file bsc_dyn_pdch.c (new file to avoid linking
issues; bsc_init.c would create undefined references, and putting in a new file
is the easiest solution).
Call dyn_pdch_init() from nm_statechg_event() whenever a TS is enabled.
Revert the |= TS_F_PDCH_MODE chunk from previous commit, since this flag will
now be set after dyn_pdch_init() sent out the PDCH ACT and when subsequently
the PDCH ACT ACK messages are received in rsl_rx_pdch_act_ack().
