Fixed error handling cases.

Thanks a lot. I pulled in all these fixes into the patch series.

I am ok with this approach.

cool.
I have done required changes to patch series and tested the same on
omap2+ boards. Can you pls test OSK5912 board boot from the below
git repo? If OSK5912 boots up(with LCD), I will post the 1st series to
LO ML.

commit 3047de5b11cc3fef9ea18a7e8d64fec7a9ea7a89

OMAP: DMA: Convert DMA library into platform driver
Convert DMA library into DMA platform driver and make use of
platform data provided by hwmod data base for OMAP2+ onwards.
For OMAP1 processors, the DMA driver in mach-omap uses resource
structures for getting platform data.
Thanks to Tony Lindgren <tony@xxxxxxxxxxx> for fixing various
omap1 issues and testing the same on OSK5912 board.

This seems to be ok.

This might require more time.
