arm64: dts: qcom: qrb4210-rb2: Fix UART3 wakeup IRQ storm

Browse Source 
Follow commit 9c92d36b0b ("arm64: dts: qcom: qrb2210-rb1: Fix UART3
wakeup IRQ storm") and apply the similar fix to the RB2 platform.

Having RX / TX pins as pull up and wakup interrupt as high-level
triggered generates an interrupt storm when trying to suspend the
device. Avoid the storm by using the falling edge trigger (as all other
platforms do).
