Samuel Ortiz 0b456c418a NFC: Remove the static supported_se field
Supported secure elements are typically found during a discovery process
initiated when the NFC controller is up and running. For a given NFC
chipset there can be many configurations (embedded SE or not, with or
without a SIM card wired to the NFC controller SWP interface, etc...) and
thus driver code will never know before hand which SEs are available.
So we remove this field, it will be replaced by a real SE discovery
mechanism.

Samuel Ortiz 73f3adb9b9 NFC: mei_phy: Register event callback when enabling the device
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.

Eric Lapuyade 4912e2fe74 NFC: mei: Add a common mei bus API for NFC drivers
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.

Samuel Ortiz cd48d8ba14 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.

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