net: airoha: npu: Read NPU wlan interrupt lines from the DTS 



Read all NPU wlan IRQ lines from the NPU device-tree node.
NPU module fires wlan irq lines when the traffic to/from the WiFi NIC is
not hw accelerated (these interrupts will be consumed by the MT76 driver
in subsequent patches).
This is a preliminary patch to enable wlan flowtable offload for EN7581
SoC.
