octphy: fix build: Revert "octphy: add support for multiple trx ids"

This reverts commit c4fc00d8515ddc9990dfaf700c501cb8fe490cab, except: we keep
the part that sets the trx_id in bts_model_phy_instance_set_defaults().

Theoretically, this patch makes a lot of sense, but in order to be able to
build osmo-bts-octphy until the headers version is clarified, revert use of
usCentreArfcn:

Above commit uses an usCentreArfcn member that is never defined in the history
of our octphy-2g-headers.git. This usCentreArfcn does exist in a code snapshot
OCTSDR-2G-02.05.00-B780-DEBUG, which is not (yet?) publicly available.

Also, the current headers version is apparently 02.07, though the octasic
version numbers have been known to cause confusion among osmocom folks.

This along with one other revert fixes this build problem:
