Add a function to match acpi devices against of_device_ids. This will be
used in the following commit ("mfd: match acpi devices against PRP0001")
to match mfd sub-devices against a of compatible string.

Not until I can see how this is going to be used.

Maybe never.

This is used directly in the following patch. Only half of the patch
series has been sent by b4, because of a limit of my email provider
(which I didn't know existed until now). I am sorry for the
inconvenience.

The patch series has been resent via the b4 relay.
You can take a look at [1] to see how it is used.
