Hi Tero

There is no need to provide the CM base address through a low-level API
from the low-level IO init, as this information is available through DT.
Re-routed the parsing function to be called from the CM drivers also to
simplify the implementation under io.c.

This one breaks boot on OMAP2430 (and presumably all other OMAP2xxx).  
Adding something like this seems to get it working.
