The ZAP region is very seldom moved around, and I wouldn't expect it
to be uncommon among the very usecase-specific 8280 machines.

Ugh. Should definitely be enabled by default.

You can keep the GMU enabled by default as well, it won't "probe" on
its own (the GPU's hw_init calls its registration)

Clock controllers have no reason to be off by default.

On sa8295p/sa8540p the GPU is powered differently, so if I leave it
enabled by default I need to disable it (or configure it) for those, or
they won't boot.

Another "messed up automotive forks" situation, eh..
Would it take a lot of new code to configure these platforms correctly?
