This fixes a bug whereby the AUART was shutdown while bytes 
were still waiting in the DMA buffer to be transmistted.

Changes since v1:
 * Split the patch in two: one to set the fifosize to the 
   DMA buffer size, and another to wait for the FIFO to empty
   before disabling the AUART.
 * The wait for the fifo to empty is now independent of DMA
   being enabled.
 * Fix bug on readl() call
 * Remove bad URL in commit log
