power_control: enable dynamic MS power control for osmo-bts

Before the recent changes, the MS Power Parameters IE would always
be included empty in RSL CHANnel ACTIVation messages iff the BTS
type is 'osmo-bts'.  Then this behavior was changed, so the user
would need to enable dynamic power control explicitly.

This is a regression, let's revert it back to the old behaviour.
