[PATCH V3 3/8] ARM: OMAP4: Re-map the CTIs IRQs from MPU to DEBUGSS

[Jon Hunter]

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].
