The "dm" command under CONFIG_CMD_DM should live under cmd/ rather than
test/dm/ so move it.

Currently, "help dm" shows as follows:

=> help dm
dm - Driver model low level access

Usage:
dm tree         Dump driver model tree ('*' = activated)
dm uclass        Dump list of instances for each uclass
dm devres        Dump list of device resources for each device

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.

Now that we may compile (but not link) code calling fixup_cmdtable when
this is not set, we need to always have the declaration available.  We
should also make sure that anyone calling the function includes
<command.h> as that's where the function declaration is.

Subcommands contain pointers to functions which are not updated when
MANUAL_RELOC is enabled. This patch fix it.

This new command can dump all device resources associated to
each device.  The fields in every line shows:
  - The address of the resource
  - The size of the resource
  - The name of the release function
  - The stage in which the resource has been acquired (BIND/PROBE)

Currently, there is no driver using devres, but if such drivers are
implemented, the output of this command should look like this:

=> dm devres
- root_driver
- soc
- extbus
- serial@54006800
    bfb541e8 (8 byte) devm_kmalloc_release  BIND
    bfb54440 (4 byte) devm_kmalloc_release  PROBE

In SPL it is sometimes useful to be able to obtain a dump of the current
driver model state. Since commands are not available, provide a way to
directly call the functions to output this information.

Adjust the existing commands to use these functions.

Unify the command for running unit tests further by moving the "dm test"
command over to "ut dm".

As well as running all tests, it is useful to be able to run a selected test.
