Subject: [PATCH 25/38] arm64: dts: mediatek: mt7986a-bpi-r3: Set interrupt-parent to mdio switch

Being this an interrupt controller, the binding forbids to use
interrupts-extended and wants an `interrupts` property instead.

Since this interrupt controller's parent is on the GPIO controller
set it as interrupt-parent and change interrupts-extended to just
interrupts to silence a dtbs_check warning.
