Juha Lumme ba486a2a29 mxs/spi: clear XFER_COUNT in ctrl0 field in DMA descriptor
On MX23 the XFER_COUNT part in ctrl0 field in DMA descriptor was
improperly OR'd during the construction of DMA descriptor chain, instead
of being freshly set.  Because of that too many bytes were being
expected from SPI during the last DMA cycle.  This caused a timeout
(SSP_TIMEOUT) to happen in the processing of the last DMA descriptor,
and thus reads and writes were failing.  This is a fix for the problem,
by clearing XFER_COUNT bytes in ctrl0 before setting the new XFER_COUNT
for DMA descriptor.
