Tegra210: Enable WDT_CPU interrupt for FIQ Debugger
This patch enables the watchdog timer's interrupt as an FIQ
interrupt to the CPU. The interrupt generated by the watchdog
is connected to the flow controller for power management reasons,
and needs to be routed to the GICD for it to reach the CPU.
