spi: qup: Fix DMA mode to work correctly

This patch fixes a few issues with the DMA mode.  The QUP needs to be
placed in the run mode before the DMA transactions are executed.  The
conditions for being able to DMA vary between revisions of the QUP.
This is due to v1.1.1 using ADM DMA and later revisions using BAM.
