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].

Data manual assigns cit0 == MA_IRQ_1 and cti1 == MA_IRQ_2
Why do you add 32 base GIC_START ?

Looks we do the same for pl310:
{ .name = "pl310", .irq = 0 + OMAP44XX_IRQ_GIC_START },

so u can ignore my comment .. excuse the noise...
