pcu_l1_if_phy: support multiple BTS (in theory)
The PCU already has a list that can hold multiple BTS objects but the
API for the direct PHY access has no way to associate a PHY with a
certain BTS object. Lets update the API so that we can associate a BTS
object when opening a PDCH.
Unfortunately OsmoPCU has never been tested with more than one BTS so it
is very likely that there are still shortcomings that prevent OsmoPCU to
work properly when more then one BTS is attached. To make users aware of
this, also print a warning as soon as more than one BTS object exists.
