HBM version 2.0 and above allows ME clients in the system to
register/unregister after the system is fully initialized.
Clients may be added or removed after enum_resp message was
received

1. To preserve backward compatibility the driver can opt-in to receive
client add messages by setting allow_add field in enum_req

2. A new client is added upon reception of MEI_HBM_ADD_CLIENT_REQ_CMD

3. A client is removed in a lazy manner when connection request
respond with MEI_HBMS_CLIENT_NOT_FOUND status

MEI bus was designed around nfc and was hard to extend.
Instead of the hard coded way of adding the devices on the mei bus
we scan the whole me client list and create a device for each
eligible me client (mei_cl_bus_rescan); currently we support
only clients with single connection and fixed address clients.
NFC radio name detection is run as a fixup routine

The patch replaces handling the device list based on struct me_cl
to device list based on me_cl_devices. The creating a connection
is pushed from the device creation time to device enablement.

Instead of holding the list of host clients (me_cl)

This way we can create host to me client connection only when needed.

In the mei bus layer there is use of different variables
of driver and device types with no clear naming convention.
There are generic struct device and struct driver,
then mei_cl_{device, driver}, and finally mei_device which
in this context serves as a bus device.

The patch sets following naming convention:

the variables of type struct device remains dev
the variables of type struct driver remains drv
the variables of type struct mei_cl_device are now cldev
the variables of type struct mei_cl_driver are now cldrv
the variables of type struct mei_device are now bus, in bus

The mei_cl_write function is giving up on a write cb ownership after it
was sent or queued. The write cb is then freed in the completion
handler. Especially during blocking write mei_cl_write function waits
for the completion handler and then access the freed memory to fetch the
written size.  The quick fix is to store the buffer size prior to
sending, the size is not altered during the flow.

 enable WT per the default BIOS setup.  However, when PAT is enabled,
 but CPU has PAT -errata, WT falls back to UC per the default values."

The CQM task events are not safe to be called from within interrupt
context because they require performing an IPI to read the counter value
on all sockets. And performing IPIs from within IRQ context is a
"no-no".

Make do with the last read counter value currently event in
event->count when we're invoked in this context.

Pull MTD fixes from Brian Norris:
 "Two trivial updates.  I meant to send these much earlier, but I've
  been preoccupied.

   - Add MAINTAINERS entry for diskonchip g3 driver

   - Fix an overlooked conflict in bitfield value assignments

  The latter update is a bit overdue, but there's no reason to wait any
  longer"
