ARM: shmobile: rcar-gen2: Use of_machine_compatible_match() helper

Browse Source 
Replace sequences of of_machine_is_compatible() calls by single calls to
the of_machine_compatible_match() helper, to simplify the code, and to
reduce code size.

Note that this does have a slight performance impact on matching
platforms: while the C sequences terminated evaluation after a match,
(internal) of_device_compatible_match() calculates a matching score, and
thus always checks against all passed compatible values.
