The Xilinx AXI Ethernet subsystem is commonly found in FPGA designs.
This patch adds a driver and device tree bindings for the Ethernet MAC
core and its MDIO controller.
The driver was tested on a RISC-V softcore in an FPGA design, with an
RGMII phy and Ethernet subsystem version 7.2 Rev. 14. Device tree
bindings match the device tree generated by Vitis hsi. Note that Vitis
generates one of the two included compatible strings depending on
version.

ethernet driver
This driver is capable of supporting basic features
of synposys dwc-xgmac ethernet MAC IP. Basic features
includes,
1. Tx and Rx, multiple Tx and Rx DMA channels, multiple
Tx and Rx queues
2. Check Sum Offloading on Tx and Rx for IPv4, IPv6,
TCP, UDP and ICMP packets
3. 10M/100M/1G speeds, Autonegotiation, Link speed
configuration, Promiscuous mode, Full/Half
duplex configuration
4. Added source files for synopsys dwc xgmac mdio driver.
synopsys dwc xgmac mdio driver fetures includes:
It supports clause 22 of IEEE 802.3 for ethernet PHY devices
management.
5. Extended mdio shell support for dwcxgmac mdio driver.

MDIO controller is part of GMAC and it requires GMAC ethernet driver to
initialize first because it will reset the whole GMAC hw block during
initialization. Both C22 and C45 APIs are supported.

Rename argument `devad` to `regad` to indicate this is the register
address in a given PHY device and to not be confused with the
Clause 45 device address within a port.

Add MDIO driver that works through GPIO pins. This driver is
useful when a microcontroller doesn't have MDIO bus or when multiple
separate MDIO buses are required. The driver provides access to
the MDIO bus through GPIO pins for any SoC that has GPIO pin control
available.

This driver implements an MDIO device. Enable the MDIO driver to avoid a
build error for:
orphan section `._device.static.3_CONFIG_MDIO_INIT_PRIORITY_'
Also set the proper compatible in mdio_shell so that the ethernet tests
build correctly.

In order to bring consistency in-tree, migrate all drivers to the new
prefix <zephyr/...>. Note that the conversion has been scripted, refer
to #45388 for more details.
