mei: bus: prefix device names on bus with the bus name
Add parent device name to the name of devices on bus to avoid device names collisions for same client UUID available from different MEI heads. Namely this prevents sysfs collision under /sys/bus/mei/device/ In the device part leave just UUID other parameters that are required for device matching are not required here and are just bloating the name.
