Currently, of_match_node compares each given match against all node's
compatible strings with of_device_is_compatible.

To achieve multiple compatible strings per node with ordering from
specific to generic, this requires given matches to be ordered from
specific to generic. For most of the drivers this is not true and also
an alphabetical ordering is more sane there.

Therefore, this patch introduces a function to match each of the node's
compatible strings against all given compatible matches without type and
name first, before checking the next compatible string. This implies
that node's compatibles are ordered from specific to generic while
given matches can be in any order. If we fail to find such a match
entry, then fall-back to the old method in order to keep compatibility.

Looks good to me. I'll put this in next for a few days. I'd really
like to see some acks and tested-by's before sending to Linus.

We could be a bit more strict here and fallback to the old matching if
the match table has any entries with name or type. I don't think that
should be necessary though.

Can you push the revert to Linus sooner, since currently a ton of boards wouldn’t be working on the PPC side, so at least -rc3 has the possibility of working for them.
