Implement trivial extension to the sandbox PHY, which makes it pretend
to support selecting USB Host mode and nothing else. Any other mode is
rejected with -EINVAL. Any submode except for default submode 0 is
rejected with -EOPNOTSUPP . The implementation behaves in this trivial
way to permit easy unit testing using test which is also added in this
commit.

To run the test, use e.g. sandbox64_defconfig and run U-Boot as follows:
$ ./u-boot -Tc 'ut dm phy_setup'

As part of bringing the master branch back in to next, we need to allow
for all of these changes to exist here.

When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay
Ethernet"' I failed to notice that b4 noticed it was based on next and
so took that as the base commit and merged that part of next to master.

This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing
changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35.

Replace instances of http://www.ti.com with https://www.ti.com

This construct is quite long-winded. In earlier days it made some sense
since auto-allocation was a strange concept. But with driver model now
used pretty universally, we can shorten this to 'auto'. This reduces
verbosity and makes it easier to read.

Coincidentally it also ensures that every declaration is on one line,
thus making dtoc's job easier.

Add driver data to existing compatible string "sandbox,phy".
Add an additional compatible string without driver_data

This will verify that bind command parses, finds and passes the
correct driver data to device_bind_with_driver_data() by using
driver_data in the second sandbox_phy_ids table entry.
In sandbox_phy_bind() a check is added to validate driver_data
content.

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.

We have a large number of places where while we historically referenced
gd in the code we no longer do, as well as cases where the code added
that line "just in case" during development and never dropped it.
