dm: Add support for handling old u-boot,dm- tags
Add a CONFIG option to deal with this automatically, printing a warning
when U-Boot starts up. This can be useful if the device tree comes from
another project.
We will maintain this through the 2023.07 release, providing 6 months
for people to notice.
