[PATCH 3/4] arm64: dts: marvell: espressobin-ultra: add PHY and switch reset pins

Both the Topaz switch and 88E1512 PHY have their reset and interrupts
connected to the SoC.

So, define the Topaz and 88E1512 reset pins in the DTS.

Defining the interrupt pins wont work as both the 88E1512 and the
Topaz switch uses active LOW IRQ signals but the A37xx GPIO controller
only supports edge triggers.
88E1512 would require special setup anyway as its INT pin is shared with
the LED2 and you first need to configure it as INT.
