power_control: enable Uplink DPC by default if format is known

So far osmo-bsc would enable Uplink DPC (Dynamic Power Control) only
for osmo-bts, and the 'static' mode for all other BTS models.  This
decision dates back to the time when ip.access specific encoding for
dynamic power control parameters was not implemented, and the MS
Power Parameters IE was sent empty in the RSL messages.

Let's make a step forward by enabling Uplink DPC by default for
all BTS models which declare the API for vendor-specific encoding
of the power control parameters.  Currently this includes osmo-bts
and nanoBTS, both supporting ip.access specific format.
