mei: bus: Initial MEI Client bus type implementation
mei client bus will present some of the mei clients
as devices for other standard subsystems
Implement the probe, remove, match, device addtion routines, along with
the sysfs and uevent ones. mei_cl_device_id is also added to
mod_devicetable.h
A mei-cleint-bus.txt document describing the rationale and the API usage
is also added while ABI/testing/sysfs-bus-mei describeis the modalias ABI.
