irqchip/tegra: Propagate IRQ type setting to parent

The LIC doesn't deal with the different types of interrupts itself
but needs to forward calls to set the appropriate type to its parent
IRQ controller.

Without this fix all IRQs routed through the LIC will stay at the
initial EDGE type, while most of them should actually be level triggered.
