Log Message:
Change the device_compatible_match() function to only perform the match.
Introduce a device_compatible_lookup() function to return an entry based
on the same matching criteria (a'la of_search_compatible()).
Update iic_compatible_match() to reflect the above change, and introduce
iic_compatible_lookup(). This pattern is less awkward to use.
