core: Default to using DEVRES outside of xPL.

After a lot of testing, I think I've traced the issue to drivers/pinctrl/mvebu/pinctrl-armada-37xx.c. There are two calls
to devm_kzalloc that, when I change to kzalloc and remove the dev
argument, my device boots again.

I cannot explain why these changes resolve the issue so I'd
appreciate if someone more knowledgeable would review.
I'm also happy to test other proposed solutions. Thank you!
