The root device should be probed just like any other device. The effect of
this is to mark the device as activated, so that it can be removed (along
with its children) if required.

lists.c / root.c do not include their own header and they
could potentially implement a different function. Therefore
actually include the headers.

In a very few cases we need to adjust the driver model root device, such as
when setting it up at initialisation. Add a macro to make this easier.

These files don't compile in some architectures. Fix it by adding the
missing headers.

using UBI and DM together leads in compiler error, as
both define a "struct device", so rename "struct device"
in include/dm/device.h to "struct udevice", as we use
linux code (MTD/UBI/UBIFS some USB code,...) and cannot
change the linux "struct device"

Add driver model functionality for generic board.

This includes data structures and base code for registering devices and
uclasses (groups of devices with the same purpose, e.g. all I2C ports will
be in the same uclass).

The feature is enabled with CONFIG_DM.
