CI: Add tests for gitlab and azure

Add tests that check that SPL can generate a standard passage on ARM and
that U-Boot proper can accept it successfully.

Cover-letter:
passage: Define a standard for firmware data flow

This series adds a standard way of passing information between different
firmware phases. This already exists in U-Boot at a very basic level, in
the form of a bloblist containing an spl_handoff structure, but the intent
here is to define something useful across projects.

The need for this is growing as firmware fragments into multiple binaries
each with its own purpose. Without any run-time connection, we must rely
on build-time settings which are brittle and painful to keep in sync.

This feature is named 'standard passage' since the name is more unique
than many others that could be chosen, it is a passage in the sense that
information is flowing from one place to another and it is standard,
because that is what we want to create.

The implementation is mostly a pointer to a bloblist in a register, with
an extra register to point to a devicetree, for more complex data. This
should cover all cases (small memory footprint as well as complex data
flow) and be easy enough to implement on all architectures.

The emphasis is on enabling open communcation between binaries, not
enabling passage of secret, undocumented data, although this is possible
in a private environment.

To try this out:

$ ./scripts/build-qemu -a arm -rsx

This will build and run QEMU for arm64 and you should see the standdard
passage working:

   Core:  49 devices, 13 uclasses, devicetree: passage

This series is available at u-boot-dm/pass-working
