One other request for this refactor.
Can you remove the usage of OMAP2_IO_ADDRESS (now gone from l-o master)
in favor of ioremap().
Here's a totally untested first pass and converting the version
currently in PM branch. Could probably use some better error
detection though, and I didn't look up exactly what size
should be ioremap'd.
