soc/tegra: pmc: Add AON SW Wake support for Tegra234

Wake-up signal 83 on Tegra234 is triggered by software writing to
WAKE_AOWAKE_SW_WAKE_TIER0_TRIGGER_0 register. This wake-up is mapped
to CPU interrupt 179 and is used by the Sensor Processing Engine (SPE)
in the Always-on (AON) power domain for waking up the system.
