Those two BTS backends never had their own MS Power Control Loop, so
they should be using the "osmo" common one. This wrong value "dsp" used
to be accepted for no good reason, but it's no longer the case. Let's
remove the line to let the backend take the default one (osmo).

It's very close to the osmo-bts-trx but without osmo-trx. Modify
the suite to make use of this BTS.
