of: Reimplement of_machine_is_compatible() using of_machine_compatible_match()
of_machine_compatible_match() works with a table of strings. of_machine_is_compatible() is a simplier version with only one string. Re-implement of_machine_is_compatible() by setting a table of strings with a single string then using of_machine_compatible_match().
