This provides an equivalent of of_fdt_match() for non-flat trees.

This is more practical than matching an array of of_device_id structs
when converting a bunch of existing users of of_fdt_match().

This is a pre-requisite for some work I'm doing to move the platform
identification in arch/powerpc until after we have unflattened the
device-tree. Rewriting all those lists as of_device_id's would be
significantly cumbersome.

Note: untested other than it compiles. I want an agreement on the
interface ASAP since the conversion of all the platforms is a burden
I'd like to avoid doing twice.

Any comments on this?

We need it as a pre-req for a powerpc series, so unless anyone yells I'll merge
it via there.

I like the idea, we already have a number of drivers that would benefit
from this.
