Dependency/merging
==================
All patches depend on the first patch, thus everything could go via
Rob's tree with people's acks.

Description
===========
Several drivers duplicate same code for getting reference to the root
node, matching it against 'struct of_device_id' table and getting out
the match data from the table entry.

There is a of_machine_compatible_match() wrapper but it takes array of
strings, which is not suitable for many drivers since they want the
driver data associated with each compatible.

Add two wrappers, similar to existing of_device_get_match_data():
1. of_machine_device_match() doing only matching against 'struct
   of_device_id' and returning bool.
2. of_machine_get_match_data() doing the matching and returning
   associated driver data for found compatible.

Best regards,
Krzysztof
