I think these will all go away with DT based booting?
So it might be worth waiting for that rather than churn
all these files, or..

..how about we pass something like struct omap_intc_data
as pdata and let the intc driver populate function pointers
for these if runtime PM calls are not enough here?

That way we could have just minimal pdata header file.
