You should be able to enable SPARSE_IRQ from the config and this
probably fixes it, this is what I saw with OMAP4 testing, not sure if it
was enabled on your config.

Currently I guess it is harmless as we don't have OMAP4 PM support
anyway, so nobody can use the PRCM interrupts on that platform anyway.
The error message itself indicates that PRCM interrupt support does not
work at all.

Other than that, the set looks good to me after your changes.
