====================
Follow-up to RGMII mode clarification: am65-cpsw fix + checkpatch

Following previous discussion [1] and the documentation update by
Andrew [2]:

Fix up the mode to account for the fixed TX delay on the AM65 CPSW
Ethernet controllers, similar to the way the icssg-prueth does it. For
backwards compatibility, the "impossible" modes that claim to have a
delay on the PCB are still accepted, but trigger a warning message.

As Andrew suggested, I have also added a checkpatch check that requires
a comment for any RGMII mode that is not "rgmii-id".

No Device Trees are updated to avoid the warning for now, to give other
projects syncing the Linux Device Trees some time to fix their drivers
as well. I intend to submit an equivalent change for U-Boot's
am65-cpsw-nuss driver as soon as the changes are accepted for Linux.
