BLZP1600 SoC includes a Synopsys gigabit Ethernet controller which
is supported by the upstream "snps,dwmac" driver.
Add a device tree entry to enable the network controller with
its associated interrupts, clocks, resets and configurations.
The Blaize CB2 board contains a TI DP83867 Phy connecting the
Ethernet controller to an RJ45 connector on the board. Add a
device tree entry for this with its associated reset via a
GPIO signal to enable Ethernet connectivity on the board.

Apologies that I missed that I missed that one, it was meant to be alphabetical, so above the gpio0 section.
