Fix TSC/BSIC handling bug and remove bts->tsc
This fixes a bug in the following circumstances:
* BSIC is set to 0 in the config file
* No TSC is explicitly specified at the BST level in the config file
In this case, we ended up using BSIC=0 and TSC=7, as TSC=7 is our
default initialization value.
The TSC of the CCCH/BCCH must always be the BCC, which is the lower 3
bits of the BSIC. Having configuration options for both the BSIC _and_
the TSC at the BTS level therefore makes no sense, as it only adds ways
in which users can configure non-oprational configurations. So we
remove the bts->tsc member, and keep only the ts->tsc members that allow
us to configure a timeslot-specific TSC that's different from the BTS
TSC (= BCC).
