Add "u-boot,dm-pre-reloc" for device nodes we want in SPL DTB
(spl/u-boot-spl.dtb).
The "soc" node (this is simple-bus node) also needs the property
to bind the pinctrl node located under it.
I am collecting this U-Boot specific hack to the bottom of board
DTS rather than inserting "u-boot,dm-pre-reloc" into SoC DTSI.
My goal is to sync DTSI with Linux for easier maintenance.

This commit imports device tree updates from Linux. It eventually
adds pinctrl-related nodes and properties.

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.

The property name of the "aliases" node should be "serial*"
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.

This commit implements the ofdata_to_platdata handler for the UniPhier
serial driver and adds serial device nodes to the device tree sources.
