In order to use the CTI interrupts inconjunction with the DEBUGSS we need to
re-map the CTI IRQs to the DEBUGSS HWMOD. The purpose for doing this is so we
can create a PMU device based upon the DEBUGSS HWMOD and use the CTI interrupts
for routing ARM PMU events for OMAP4430 devices.

This is based upon Benoit Cousson's patch [1].

As with patch 6 of this series, setting this one aside until we can take a 
closer look at the way we set up the CTI.
