As DM_ETH is required for all network drivers, it's now safe to remove
the non-DM_ETH support code.

Series-changes: 3
- revert:
  commit "3374264df97b" ("drivers: net: qe: deselect QE when DM_ETH is enabled")
  as now qe works with DM and DM_ETH support.
- fix mailaddress from Holger

Series-changes: 2
- add comments from Qiang Zhao:
  - add device node documentation
  - I did not drop the dm_qe_uec_phy.c and use drivers/net/fsl_mdio.c
    because using drivers/net/fsl_mdio.c leads in none existent
    udevice mdio@3320
    instead boards with DM ETH support should use now this
    driver.
- remove RFC tag

Commit-notes:

- I let the old none DM based implementation in code
  so boards should work with old implementation.
  This Code should be removed if all boards are converted
  to DM/DTS.

- add the DM based qe uec driver under drivers/net/qe

- Therefore copied the files uccf.c uccf.h uec.h from
  drivers/qe. So there are a lot of Codingstyle problems
  currently. I fix them in next version if this RFC
  patch is OK or it needs some changes.

- The dm based driver code is now under drivers/net/qe/dm_qe_uec.c
  Used a lot of functions from drivers/qe/uec.c

- seperated the PHY specific code into seperate file
  drivers/net/qe/dm_qe_uec_phy.c

END

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, arch/${ARCH}/include/asm/errno.h and include/linux/errno.h have
the same content.  (both just wrap <asm-generic/errno.h>)

Replace all include directives for <asm/errno.h> with <linux/errno.h>.

We are supposed to use #include <...> to include headers in the
public include paths.  We should use #include "..." only for headers
in local directories.

As the QE firmware struct is shared with Fman, move the header file
