osmo-bts-trx/scheduler: also detect TSC for Access Bursts on PDCH
If a logical channel, on which an Access Burst has been received,
is not either of RACH, PDTCH or PTCCH, then this is a handover
Access Burst, which is always encoded as 8-bit and shall contain
the generic training sequence (TS0).
Access Bursts on a PDCH time-slot are not related to handover.
