commit 91685096f8eae4a0be2b3bd2a773259c516897de
Author: Philipp Maier <pmaier at sysmocom.de>

    bts: revert trx shutdown order
    
    When a new TRX is allocated using gsm_bts_trx_alloc() (see gsm_data_shared.c in
    openbsc.git), than it is added to the list in order. When octphy is shutting
    down the BTS, it uses llist_for_each_entry() to iterate the tansceiver list to
    shut all transceivers down. This means it starts the shut down process with
    the primary TRX and then continues with the secondary transceivers in order.
    
    However, octphy does not allow to close primary TRX if the secondary TRX is
    open. The shutdown sequence must begin with the secondary transceivers and
    finish with the primiary transceiver as last item.
    
    The problem can be easily fixed by iterating the transceiver list in reverse
    order using llist_for_each_entry_reverse() instead of llist_for_each_entry()
    
    Since this is a change in the common code, all BTS models (not only octphy)
    are affected, but from the logical perspective, this change makes sense
    for all other BTS models too.
