The old reset controller work was abandoned, and it won't be resurrected 
before we have:

a) hwmod clock driver merged (which is under reviews atm)
b) OMAP interconnect driver merged (which is under work by Tony)

I believe you need to introduce platform data callbacks for reset 
handling until this is resolved, and call hwmod reset functionality 
directly.
