of: base: make of_device_compatible_match() accept const device node

of_device_is_compatible() accepts const device node pointer, there is no reason why of_device_compatible_match() can't do the same. Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com> Link: https://lore.kernel.org/r/YzY5MaU5N4A2st5R@google.com Signed-off-by: Rob Herring <robh@kernel.org>
