irqchip/tegra: Propagate IRQ type setting to parent

lynxeye-dev · KAGA-KOKO · commit 209da3915483 · 2015-10-26T09:20:59.000+09:00
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.
