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.

This allows to scan the DT including all "clocks" node's sub-nodes
in which fixed-clock are defined.
All fixed-clock should be defined inside a clocks node which collect all
external oscillators. Until now, all clocks sub-nodes can't be binded except
if the "simple-bus" compatible string is added which is a hack.
Update test.dts by moving clk_fixed node inside clocks.

Some tests require either livetree or flat tree. Add flags to allow the
tests to specify this. Adjust the test runner to run with livetree (if
supported) and then flat tree.
Some video tests are quite slow and running on flat tree adds little extra
test value, so run these on livetree only.

It is useful to run the driver model tests with both livetree and flat

Running a new test should reset the sandbox state to avoid tests
interferring with each other. Move the existing state-reset code into a
function so it can be used from tests.
Also update the code to reset the SPI devices and adjust the test code to

The ut command prints a test failure count each time it is executed.
This is stored in a global variable which is never reset. Consequently,
the printed failure count accumulates across runs. Fix this by clearing
the counter each time "ut" is invoked.

All driver model tests have a dm_test_ prefix. Ignore it when matching a
test name. This makes it easier to run individual tests, like this:
./sandbox/u-boot -d ./sandbox/arch/sandbox/dts/test.dtb \
-c "ut dm clk_periph"
We can use 'clk_periph' instead of 'dm_test_clk_periph'.
Also print a message if the requested test is not found.

There's not much point in having a failure count if we always give up on

The file test.dts from driver model test directory,
was compiled by call dtc in script: test/dm/test-dm.sh.
This doesn't allow for including of dtsi files and using

Since the mentioned script builds U-Boot before tests,
then moving the test.dts file into sandbox dts directory
is reasonable.

Driver model currently only operates after relocation is complete. In this
state U-Boot typically has a small amount of memory available. In adding
support for driver model prior to relocation we must try to use as little
memory as possible.
In addition, on some machines the memory has not be inited and/or the CPU
is not running at full speed or the data cache is off. These can reduce
execution performance, so the less initialisation that is done before
relocation the better.
An immediately-obvious improvement is to only initialise drivers which are
actually going to be used before relocation. On many boards the only such
driver is a serial UART, so this provides a very large potential benefit.
Allow drivers to mark themselves as 'pre-reloc' which means that they will
be initialised prior to relocation. This can be done either with a driver
flag or with a 'dm,pre-reloc' device tree property.
To support this, the various dm scanning function now take a 'pre_reloc_only'
parameter which indicates that only drivers marked pre-reloc should be
bound.

Add some tests of driver model functionality. Coverage includes:
- basic init
- binding of drivers to devices using platform_data
- automatic probing of devices when referenced
- availability of platform data to devices
- lifecycle from bind to probe to remove to unbind
- renumbering within a uclass when devices are probed/removed
- calling driver-defined operations
- deactivation of drivers when removed
- memory leak across creation and destruction of drivers/uclasses
- uclass init/destroy methods
- automatic probe/remove of children/parents when needed
This function is enabled for sandbox, using CONFIG_DM_TEST.
