pata-bf54x: Set ATAPI HSM to control IDE device terminate sequence.
Set ATAPI host state machine to control IDE device terminate sequence.
Some IDE harddisk may assert terminate sequence in the middle of a
formal DMA transaction and resume later. Bit DETECT_TERM in ATAPI_CTRL
register determines whether the ATAPI host state machine or the kernel
driver should take care of this case.
