NFC: microread: Fix mei physical layer
The MEI bus API changed according to the latest comments from the char-misc
maintainers, and this patch fixes the microread mei physical layer code
according to those changes:
We pass the MEI id back to the probe routine, and the mei_driver takes a
table of MEI ids instead of one static id.
Also, mei_bus_driver got renamed to mei_driver, mei_bus_client to
mei_device, and mei_bus_set/get_clientdata to mei_set/get_clientdata.
