The PDK2 board is capable of running both 100M and 1G ethernet. However,
the i.MX6 has only one ethernet MAC, so it is possible to configure
either 100M or 1G Ethernet. In case of 100M option, the PHY is on the
SoM and the signals are routed to a RJ45 port. For 1G the PHY is on
the PDK2 board with another RJ45 port. 100M and 1G ethernet use
different signal pins from the i.MX6, but share the MDIO bus.
This SoM board combination is used to demonstrate how to enable 1G
ethernet configuration.

During the conversion of this board to DM_REGULATOR, usb-mass-storage
was broken and started failing with the following error:
=> ums 0 mmc 2
UMS: LUN 0, dev 2, hwpart 0, sector 0x0, count 0xe90000
Error enabling VBUS supply
g_dnl_register: failed!, error: -38
g_dnl_register failed
Fix this by adding the relevant GPIO to the regulator node.

Use DM_ETH instead of legacy networking. Add VIO as a fixed regulator
to the relevant device-trees and augment the FEC node with properties
for the reset GPIO.
It should be noted that the relevant properties for the reset GPIO
already exist in the PHY node (reset-gpios, reset-delay-us,
reset-post-delay-us) but U-Boot currently ignores those and only
supports the bus-level reset properties in the FEC node
(phy-reset-gpios, phy-reset-duration, phy-reset-post-delay).
