It's supposed to give only 16550 compatibility mode with a 1K fifo.  I
think the large fifo got lost in porting.
(FIFO_DMA_MODE | ... | FIFO_RX_MEDH) gets uselessly (?) written to the
fifo control register but com->fifo_image doesn't get initialized to
match; it is initialized later with different values.  I can't test
this.
