When trying to get rid of the obsolete VLYNQ bus, Jonas and Florian
pointed out that its only user, the AR7 platform can probaly go entirely
[1]. This series does exactly that. Even OpenWRT has removed support
because these devices are "stuck with 3.18" [2].

It removes the drivers first, because watchdog and network include
platform specific headers. Once the drivers are gone, we remove the
platform. The patches are based on 6.6-rc2 and created with
"--irreversible-delete" to save some space.

My suggestion is that everything is merged via the MIPS tree in one go,
so we don't have broken drivers because of missing platform headers. But
maybe there are reasons for a two-cycle removal with the drivers first
and the platform later?

Looking forward to comments.

Happy hacking,

   Wolfram

AR7 is going to be removed from the Kernel, so remove its networking
support in form of the cpmac driver. This allows us to remove the
platform because this driver includes a platform specific header.
