[PATCH v2 00/14] net: ldpaa_eth: transition to CONFIG_DM_ETH

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:

=> dm tree

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