add a VTY command for activating PDCH channels (in EGPRS mode)

This allows us to do RF measurements (EDGE EVM and the like) even
without having any PCU/RLC/MAC code as of now.

To use it, configure PDCH type timeslots (e.g. TS 7) in the BSC and then
use "trx 0 7 activate 0" to manually activate the PDTCH lchan on top
of that timeslot.  The BTS will now happily transmit EDGE/8PSK data.
