bus: mvebu-mbus: Restore checking for coherency fabric hardware
The new mvebu-mbus driver was not checking the device tree for coherency fabric hardware and hence was not setting the hw_io_coherency flag in mbus_state. This prevented the mvsdio driver from operating correctly. This patch restores the check. Signed-off-by: Neil Greatorex <neil@fatboyfat.co.uk> Signed-off-by: Jason Cooper <jason@lakedaemon.net>
