When a DMA transfer is done (ie all bytes have been transfered), the corresponding Terminal Count bit must be set in the status register. This bit is already cleared in i8257_read_cont and i8257_write_cont when required. This fixes (at least) floppy transfer in IBM 40p firmware, which checks in DMA controller if everything went fine.
