frequency generated by the controller.

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.

Initialize the MDIO peripheral clock (normally done during GMAC
initialization) before trying any MDIO transfers, preventing startup
errors.

Updates Ethernet PHY devicetree bindings to be more consistent with
Linux by using the standard `reg` property for the PHY address instead
of a custom `address` property. As a result, MDIO controller bindings
now require standard `#address-cells` and `#size-cells` properties.

Add `mdio_read_c45()`/`mdio_write_c45()` APIs for Clause 45 access
and remove the `protocol` MDIO binding property so that MDIO bus
controller can support more than one protocol.
A new MDIO header is introduced with generic opcodes, MMD and
registers addresses, to be used by MDIO and PHY drivers.
Existing MDIO drivers that support both Clause 22 and Clause 45
access are migrated to the new APIs.

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.

Adds MDIO driver. Works via exposed
ADIN2111 functions.
It is possible to access Clause 45 and 22 registers.
Due to MDIO API limitation Clause 45 access
is done using driver specific MDIO functions.
Provides API and functions for PHY driver.

Arm fvp_baser_aemv8r and fvp_base_revc_2xaemv8a boards are using
SMSC91C111 as their ethernet adapters.
Portions of the codes are based on FreeBSD code from its
'src/sys/dev/smc/if_smc.c' and 'src/sys/dev/smc/if_smcreg.h'.
This driver has two parts, one is the ethernet controller driver, which
is MAC layer driver. The other is the MDIO driver, which is the PHY
layer driver. Both of them are in the same source file due to that they
need to share the same reading and writing register functions and
the smsc object.
The mdio driver is needed by the existing 'phy_mii' driver, which is
a driver for the generic MII-compliant PHY.
This driver was developed under the fvp_base_revc_2xaemv8a target and
has been tested on the fvp_baser_aemv8r target.

DTS property attributes are (by default) not required.
Explicitly specifying `required: false` is redundant.
Perhaps a warning to that effect would be useful.
