With [1] removing MPCore SMP support, this makes the OX820 barely usable,
associated with a clear lack of maintainance, development and migration to
dt-schema it's clear that Linux support for OX810 and OX820 should be removed.

In addition, the OX810 hasn't been booted for years and isn't even present
in an ARM config file.

For the OX820, lack of USB and SATA support makes the platform not usable
in the current Linux support and relies on off-tree drivers hacked from the
vendor (defunct for years) sources.

The last users are in the OpenWRT distribution, and today's removal means
support will still be in stable 6.1 LTS kernel until end of 2026.

If someone wants to take over the development even with lack of SMP, I'll
be happy to hand off maintainance.

The plan is to apply the first 4 patches first, then the drivers
followed by bindings. Finally the MAINTAINANCE entry can be removed.

I'm not sure about the process of bindings removal, but perhaps the bindings
should be marked as deprecated first then removed later on ?

It has been a fun time adding support for this architecture, but it's time
to get over!

Nah, just remove them. Like the code, we can always bring them back if 
needed.
