4218456b3f vbe: Add Kconfig options for VPL
Enable the various features needed in VPL, by adding Kconfig options.

Update the defconfig for sandbox_vpl so that the build for each phase
includes what is needed. Drop LZMA for now and make sure partition support
is omitted in SPL, since it is not needed.

c263e21bcb vbe: Move OS implementation into a separate file
Move this into its own file so it can be built only by U-Boot proper.

98bedf42ea vbe: Rename vbe_fixup to vbe_request
The vbe_fixup file handles device tree fixups, but these are called OS
requests in VBE. Rename the file to reflect its wider purpose.

5fe72d968f event: Drop the path when checking event-list filenames
This path does not seem to be present in clang-14 for some reason. Relax
the regular expression so that the test works, at least for non-LTO.

8aaacd6136 vbe: Add fixups for a basic set of OS requests
As a starting point, add support for providing random data, if requested
by the OS. Also add ASLR, as a placeholder for now.

(fixed up to use uclass_first_device_err() instead)

cb47e21acb vbe: Support VBE simple
Add support for VBE simple, which permits firmware update of a single
image stored in MMC or another block device.

98887ab802 event: Add an event for device tree fixups
At present there is a confusing array of functions that handle the
device tree fix-ups needed for booting an OS. We should be able to switch
to using events to clean this up.

As a first step, create a new event type and call it from the standard
place.

Note that this event uses the ofnode interface only, since this can
support live tree which is more efficient when making lots of updates.

9de3773a5c event: Add a script to decode the event-spy list
For debugging and dicoverability it is useful to be able to see a list of
each event spy in a U-Boot ELF file. Add a script which shows this, along
with the event type and the source location. This makes events a little
easier to use than weak functions, for example.

Add a basic sandbox test as well. We could provide a test for other
boards, but for now, few use events.
