At present, many of the NXP S32 shim drivers do not make use of
devicetree instance-based macros because the NXP S32 HAL relies on an
index-based approach, requiring knowledge of the peripheral instance
index during both compilation and runtime, and this index might not
align with the devicetree instance index.
The proposed solution in this patch eliminates this limitation by
determining the peripheral instance index during compilation
through macrobatics and defining the driver's ISR within the shim
driver itself.
Note that for some peripheral instances is needed to redefine the
HAL macros of the peripheral base address, since the naming is not
uniform for all instances.

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.

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.

Introduce NXP S32 NETC External MDIO controller driver. Driver supports
a single instance, as current support is based on NXP S32Z/E SoCs.
