Introduce BTS feature BTS_FEAT_MS_PWR_CTRL_DSP
It indicates whether BTS model supports managing an MS Power Control Loop over HW/DSP instead of using the software based osmocom algorithm present in osmo-bts. osmo-bts-trx own loop implementation is considered to be a "DSP/HW" one since it acts on lower layers and interferes with osmocom algorithm since it controls the same end variable "lchan->ms_power_ctrl.current", this way we make sure both aren't enabled at the same time. Old behavior in kept: if common upper-layer algo is not enabled explicitly in VTY (ms-power-control osmo) and bts-trx specific lower layer algo is neither enabled (osmotrx ms-power-loop <xyz>), then no power control is done at all. Related: OS#1851 Change-Id: I49706926b1e962b18791174627bc3cc0cd0cd9d5
