Revert "Merge patch series "arm: dts: am62-beagleplay: Fix Beagleplay Ethernet""

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.

board: atmel: fix pda variable not being reset

In case someone detects a PDA and u-boot sets the 'pda' variable,
and the user does a saveenv, the pda is set in env, and if the
screen is removed, u-boot will still have in the env the 'pda'
variable, even if no screen is attached.
In order to fix this, we have to reset the 'pda' variable,
such that it's not just set if the screen is detected, but also unset
if no screen is detected.

board: atmel: add support for pda detection

This adds the support for PDA detection as common code for
Atmel boards.
Using the one wire interface over GPIO , an EEPROM memory is read

and TM7000B.
Once the PDA is detected, an environment variable is set accordingly.

SPDX: Convert all of our single license tags to Linux Kernel style

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.

board: atmel: fix pda variable not being reset

In case someone detects a PDA and u-boot sets the 'pda' variable,
and the user does a saveenv, the pda is set in env, and if the
screen is removed, u-boot will still have in the env the 'pda'
variable, even if no screen is attached.
In order to fix this, we have to reset the 'pda' variable,
such that it's not just set if the screen is detected, but also unset
if no screen is detected.

board: atmel: fix pda variable not being reset

In case someone detects a PDA and u-boot sets the 'pda' variable,
and the user does a saveenv, the pda is set in env, and if the
screen is removed, u-boot will still have in the env the 'pda'
variable, even if no screen is attached.
In order to fix this, we have to reset the 'pda' variable,
such that it's not just set if the screen is detected, but also unset
if no screen is detected.

board: atmel: fix pda variable not being reset

In case someone detects a PDA and u-boot sets the 'pda' variable,
and the user does a saveenv, the pda is set in env, and if the
screen is removed, u-boot will still have in the env the 'pda'
variable, even if no screen is attached.
In order to fix this, we have to reset the 'pda' variable,
such that it's not just set if the screen is detected, but also unset
if no screen is detected.
