sysmobts: fully support trx_power_params
The simplistic approach of sysmobts_get_nominal_power() is insufficient
to cope for devices that have an internal PA. The Actual transceiver
board is driven to a certain level (0..23 dBm typically), and the
external PA must be handled independent of that. Increasing the return
value of sysmobts_get_nominal_power() would result in the sysmoBTS
mainboard attempting to reach a higher power, which is wrong.
This change affects sysmoBTS 1020 and 1100. It causes power-ramping to
be used by default. For 1002 and 2050, no behavior change is expected.

tx_power: Change PA calibration tables to use delta vales
It seems more user friendly to look at a calibration table in terms of
the delta (positive or negative) compared to the nominal gain value,
rather than a collection of absolute gain values. It has the added
benefit that the (API/data model) user doesn't have to specify a gain
value for each ARFCN, but rather can rely on the default nominal gain in
absence of a calibration table for this specific unit.
