The target index can be used by userspace to uniquely identify a target
and thus should be kept unique, per NFC adapter. Moreover, some protocols
do not provide a logical index when discovering new targets, so we have to
generate one for them.
For NCI or pn533 to fetch their logical index, we added a logical_idx field
to the target structure.

The whole code around eeprom is distributed
across whole bunch of different files, most
of which belong to the to-be-DVM code. As a
result, it is currently very hard to split
out the EEPROM code to be generic. However,
it is also quite unlikely that the current
EEPROM code will be needed by the MVM code
as that has different mechanisms to query
the EEPROM (it does so through the uCode.)

So, at least temporarily, move everything
into priv. If it becomes necessary to use
the code from MVM, we will have to split it
out, but then it's also easier since we'll
know what pieces we need.

Split the force_reset debugfs file into two
different files:
 * "rf_reset" triggers a reset of the RF when
   written to and exposes statistics on RF
   resets when read
 * fw_restart triggers a firmware restart when
   written to and lives in the transport

This cleans up all sources of firmware restart
to originate within the transport layer and
allows us to simplify some code.

This removes one of the two sources of device
restarts in the upper layer -- those are a bit
inconvenient because normal restarts originate
in the transport. By moving the watchdog down
it can be treated the same.

Also rewrite the watchdog logic. Timers are
much more efficient when they never fire, so
instead firing a timer every 500ms set up a
timer for each TX queue and fire it only when
the queue is really stuck. This avoids the CPU
waking up when everything is working well.

While at it, remove the wd_disable config item
and replace it by simply setting wd_timeout to
IWL_WATCHHDOG_DISABLED (0).

That way it isn't needed in hw_params, which
is shared data. It also isn't really what we
should configure in the transport, that is
better just 4k/8k, so configure a bool and
derive the page order in the transport. This
also means the transport doesn't need access
to the module parameter any more.

CHIP_92D_{C,D}_CUT with conflicting values for the C and D cut versions,
and literal hex values were used in the IS_92D_{C,D,E}_CUT macros.  So
we clean all this up and in doing so enable cut-specific code paths for
cuts C and D, which would not have been executed because the
CHIP_92D_{C,D}_CUT constants were wrong and the cut version was thus
recorded incorrectly.
