The autoboot tests are a recent addition to U-Boot, providing much-needed
coverage in this area.
A side effect of the keyed autoboot test is that this feature is enabled
in sandbox always. This changes the autoboot prompt and confuses the
pytests. Some tests become slower, for example the vboot tests take about
27s now instead of 3s.
We don't actually need this feature enabled to be able to run the tests.
Add a switch to allow sandbox to turn it on and off as needed. Use this
in the one test that needs it.
Add a command-line flag in case this is desired in normal use.

state_uninit() and dm_uninit() are mutually exclusive:
state_uninit() prints via drivers. So it cannot be executed after
dm_uninit().
dm_uninit() requires memory. So it cannot be executed after state_uninit()
which releases all memory.
Just skip dm_uninit() when resetting the sandbox. We will wake up in a new
process and allocate new memory. So this cleanup is not required. We don't
do it in sandbox_exit() either.
This avoids a segmentation error when efi_reset_system_boottime() is

Running 0 driver model tests
Failures: 0
At present there are no SPL unit tests.
Note that there is one wrinkle with these tests. SPL has limited memory
available for allocation. Also malloc_simple does not free memory
(free() is a nop) and running tests repeatedly causes driver-model to
reinit multiple times and allocate memory. Therefore it is not possible
to run more than a few tests at a time. One solution is to increase the
amount of malloc space in sandbox_spl. This is not a problem for pytest,
since it runs each test individually, so for now this is left as is.

At present if one of the initcalls fails on sandbox the address printing
is not help, e.g.:
initcall sequence 0000557678967c80 failed at call 00005576709dfe1f (err=-96)
This is because U-Boot gets relocated high into memory and the relocation
offset (gd->reloc_off) does not work correctly for sandbox.
Add support for finding the base address of the text region (at least on
Linux) and use that to set the relocation offset. This makes the output
better:
initcall sequence 0000560775957c80 failed at call 0000000000048134 (err=-96)
Then you use can use grep to see which init call failed, e.g.:
$ grep 0000000000048134 u-boot.map

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.
