Use a manual test for the VBE test, so we can make the pytest and the
C unit test work together properly.

At present we put the driver in the /chosen node in U-Boot. This is a bit
strange, since U-Boot doesn't normally use that node itself. It is better
to put it under the bootstd node.

To make this work we need to copy create the node under /chosen when
fixing up the device tree. Copy over all the properties so that fwupd
knows what to do.

Update the sandbox device tree accordingly.

We don't need the U-Boot prefix on the version and in fact it is harmful
since pytest gets confused seeing the U-Boot banner bring displayed when
the version is printed.

Drop the prefix from the string.

We could produce an entirely new string from the component parts, but this
adds to the rodata size and would break the use of version_string as the
only thing which holds this information.

We want to be able to mark an image as related to a phase, so we can
easily load all the images for SPL or for U-Boot proper.

Add this to the FIT specification, along with some access functions.

Some tests currently return 0 when they want to be skipped. Update them to
return -EAGAIN instead, so they are counted as skipped.

A few tests are in two parts, with the latter part being skipped in
certain situations. Split these into two and use the correct condition for
the second part.

When a FIT includes some OS requests, U-Boot should process these and add
the requested info to corresponding subnodes of the /chosen node. Add a
pytest for this, which sets up the FIT, runs bootm and then uses a C
unit test to check that everything looks OK.

The test needs to run on sandbox_flattree since we don't support
device tree fixups on sandbox (live tree) yet. So enable BOOTMETH_VBE and
disable bootflow_system(), since EFI is not supported on
sandbox_flattree.

Add a link to the initial documentation.

To avoid duplicating code, create a new fit_util module which provides
various utility functions for FIT. Move this code out from the existing
test_fit.py and refactor it with addition parameters.

Fix up pylint warnings in the conversion.

This involves no functional change.

This information needs to be set up by the bootstd tests as well. Move it
into a common function and ensure it is executed before any bootstd test
is run.

Make sure the 'images' parameter is set correctly for fixups.

There is a number of users that use uclass_first_device to access the
first and (assumed) only device in uclass.

Some check the return value of uclass_first_device and also that a
device was returned which is exactly what uclass_first_device_err does.

Some are not checking that a device was returned and can potentially
crash if no device exists in the uclass. Finally there is one that
returns NULL on error either way.

Convert all of these to use uclass_first_device_err instead, the return
value will be removed from uclass_first_device in a later patch.
