Brian Niebuhr d3f7141cbf spi: davinci: do not use temporary buffer if no transmit data provided 
Remove usage of temporary buffer when no transmit data is provided.
Instead, use the transmit register itself as the source of data.

By choosing the transmit register itself as the source of data, this
patch helps remove unnecessary accesses to memory when no real data
is being transmitted.
