Minor patches remaining after EDMA series was posted.

First patch adds the TI_EDMA option which people can forget to add and
can result in failure without any informative errors of why DMA is not
working. There was a discussion on avoiding Kconfig and putting this in
the defconfig instead.

Second patch adds comments to the EDMA code for the calculations in the
A-sync case. From my experience, this code is not-so-obvious. Hopefully
this makes the life of readers of the code a little better.
