ARM: dts: qcom-msm8974: change invalid flag IRQ NONE to valid value

Change the third field of the "interrupts" property from
IRQ_TYPE_NONE to the correct value.

I do not have hardware documentation for these devices, so I
followed a mail list suggestion to copy the flag values from the same
type of node in arch/arm64/boot/dts/qcom/msm8916.dtsi
