misc-mods Fix irq registering for tegra mods

Browse Source 
Summary: Support to hook mods interrupts
for tegra mods devices was broken due to
gpu-mods changes that went uncaught in sanity.
This change modifies the kernel to allow the tegra
code paths to work again. This change also adds
support to map irq numbers to gpio input pins
to expand functionality in the irq framework.
