Enabling and disabling device is exclusively handled by the mei_phy_ops.

The callback registration starts a waiting read, so it needs to be fired
everytime the device is enabled. Otherwise following writes will never get
an answer back.

This isolates the common code that is required to use an mei bus nfc
device from an NFC HCI drivers. This prepares for future drivers for
NFC chips connected behind an Intel Management Engine controller.
The microread_mei HCI driver is also modified to use that common code.

This reverts commit 63cd353c.

We no longer need this fix as the MEI bus APIs are now merged into
char-misc-next.

The mei_device field should be called device, not mei_device.

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.

On some peculiar worlds, microreads are found hidden behind MEIs and needs
to be accessed through the ME bus.
