Thierry Escande 7cbe0ff3e4 NFC: Add a nfc hardware simulation driver
This driver declares two virtual NFC devices supporting NFC-DEP protocol.
An LLCP connection can be established between them and all packets sent
from one device is sent back to the other, acting as loopback devices.

Once established, the LLCP link can be disconnected by disabling the target
device (with rfkill, nfctool, or neard disable-adapter test script).

Samuel Ortiz d999e4db0a NFC: mei_phy depends on INTEL_MEI
INTEL_MEI_BUS_NFC never made it upstream, so make it depend on INTEL_MEI.

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 aa74103071 NFC: pn544: Separate the core code and the i2c one into different modules
As we may need to support other physical layers, we can avoid linking the
core part into each and every pn544 module.

Eric Lapuyade 412fda538f NFC: Changed HCI and PN544 HCI driver to use the new HCI LLC Core
The previous shdlc HCI driver and its header are removed from the tree.
PN544 now registers directly with HCI and passes the name of the llc it
requires (shdlc).
HCI instantiation now allocates the required llc instance. The llc is
started when the HCI device is brought up.

Eric Lapuyade bbed0deefb NFC: HCI based pn544 driver
This is an NFC driver for NXP pn544.
Unlike pn544.c, this one is based on the NFC HCI and SHDLC kernel layers.

Randy Dunlap ed46fdfc54 nfc: NFC_WILINK depends on NFC_NCI
nwcwilink.c uses nci_*() interfaces, so it should depend on
NFC_NCI.

Fixes these build errors:
