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.

mei: bus: add more client attributes to sysfs Export more client attributes via sysfs that are usually obtained upon connection. In some cases, for example a monitoring application may wish to know the attributes without actually performing the connection.
