platform_device_register_simple() copies *res by value, so I believe we can
make res[] static __initdata.  This way we don't need to evaluate the array
on the stack at runtime, and the data gets discarded after initcalls have
run.

Can you please review and test the below?  I had a go but wasn't able to
fumble my way to a suitable config (I hope):
