l1_if: if ul_power_target==0, hard-code MS power to what RSL says
RSL CHAN ACT contains a MS_POWER IE which is intended to be used as the
initial power level for the MS, before the UL power control loop is
starting.
In our case, if ul_power_target != 0, then the DSP takes care of power
control. If ul_power_target == 0, then we instruct the phone to
constantly use the value specified by the BSC in the MS_POWER IE.
FIXME: Actually implement a proper power control algoritihm inside
osmo-bts so we don't have to rely on the DSP implementation.
