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
