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.
