[ARM] tegra: add suspend and mirror irqs to legacy controller

mirror IRQ enable and disable operations on the legacy PPI system
interrupt controller, since the legacy controller is responsible
for responding to wakeup interrupts when the CPU is in LP2 idle mode

save the irq controller state on suspend and restore on resume
