This patch set targets to add support for CONFIG_DM_ETH in DPAA2 based SoCs. We start by adding a DM MDIO driver for the MDIO interface found on the mEMAC. The next two patches start the transition of the ldpaa_eth and fsl-mc drivers towards using the 'struct udevice' and probing on DTS nodes.
Any unnecessary configurations made for the DPAA2 ethernet devices are compiled out when CONFIG_DM_ETH. This is because any information necessary is available in its associated DTS node.
For the moment, only configs of RDB boards are transitioned to CONFIG_DM_ETH since its more of a straightforward move than for the QDS ones.
As an example, the 'dm tree' output for a LS2088ARDB board looks something like the following:

Changes in v2: - used the positive logic (ifdef CONFIG_DM_ETH instead of ifndef) - refactor the mdio read/write code for code reuse
