[PATCH 1/2] arm64: dts: uDPU: fix broken ethernet

[Russell King]

The uDPU uses both ethernet controllers, which ties up COMPHY 0 for
eth1 and COMPHY 1 for eth0, with no USB3 comphy.  The addition of
COMPHY support made the kernel override the setup by the boot loader
breaking this platform by assuming that COMPHY 0 was always used for
USB3.  Delete the USB3 COMPHY definition at platform level, and add
phy specifications for the ethernet channels.

Fixes: bd3d25b07342 ("arm64: dts: marvell: armada-37xx: link USB hosts with their PHYs")
