Device Tree really improves code maintainability and is now
available for SPL too.

This is the state-of-the-art implementation in U-boot.

The board files (platform data) are no longer needed.

The current GPL only licensing on the device trees makes it very
impractical for other software components licensed under another
license.

To make it easier to reuse them, the device trees for UniPhier
SoCs and boards have already been dual-licensed in Linux.

Follow this trend in U-boot too.

This EEPROM chip is installed on the expansion board commonly used
on UniPhier platform.  To avoid duplicated description, move the
EEPROM node to a separate file and include it from other device tree
sources.

to assign a desired number for the device sequence number.

If CONFIG_OF_CONTROL is defined, search device tree nodes that are
compatible with "panasonic,uniphier-ehci" and take the base address
from their "reg" property.
