Justin T. Gibbs ed69a71305 Change the way DMA is handled during the command phase. Only test on 
SDONE, not HDONE.

In the data phase dma handler, mask off just the enable bits instead of
clearing the whole register.  Clearing the direction bit could be bad.
Also don't stop a DMA until MREQPEND goes false.  Doing this may cause
an ABORT on the PCI bus although I have yet to see this happen.

Add definitions for MREQPEND and the BRDCTL register.  The BRDCTL register
is used to handle high byte termination and automatic termination testing.
