arm64: dts: qcom: sa8775p-ride: Describe sgmii_phy0 irq

There's an irq hooked up, so let's describe it.

Prior to commit 9757300d
("pinctrl: qcom: Add intr_target_width field to support increased number of interrupt targets")
one would not see the IRQ fire, despite some (invasive) debugging
showing that the GPIO was in fact asserted, resulting in the interface
staying down.

Now that the IRQ is properly routed we can describe it.
