[PATCH] rockchip: arm64: dts: rockchip: Fix incorrect interrupt for the 9Tripod X3568 v4

[Coia Prant]

The recently changes for 9Tripod X3568 mistakenly configured
the WiFi host-wake interrupt trigger type as IRQ_TYPE_LEVEL_LOW.

However, the associated pin `wifi_host_wake_irq` is configured
with an internal pull-down resistor.

When the WiFi module enters a low-power sleep state and leaves
the pin floating, this pull-down bias drives the pin low.

Since the interrupt is incorrectly set to level-low, this combination
traps the kernel in an endless interrupt loop.

Correct the interrupt trigger type to IRQ_TYPE_LEVEL_HIGH based on the
actual hardware logic: the pin is kept low by default and driven high by
the WiFi module to wake up the host.
