    sysmobts: Don't start with 0dBm TRX output power before ramping
    
    In case a system has a high-gain external PA (like a 40dB PA) connected
    externally, we cannot simply switch the transceiver to 0 dBm in
    trx_init() only to then start the ramping at much lower levels once the
    PHJ completes in trx_init_compl_cb().  The result would be a short
    0 + 40 dBm spike followed by later ramping.  We want to avoid that
    spike, particularly its associated inrush current, so let's bring up the
    board with smething very conservative like -50 dBm, and then ramp from
    there.
