In iwl_fw_ini_get_trigger_len the driver allocates space for memory
regions regardless of their domain and in iwl_fw_ini_dump_trigger the
driver aborts trigger collection of disabled domain. This diff causes
unneeded memory allocation and traling zeros in the dump file.

Solve this behavior by enforcing domain checking in
iwl_fw_ini_get_trigger_len

In the dump info, the driver sets device_family to
IWL_FW_ERROR_DUMP_FAMILY_7 in case IWL_FW_ERROR_DUMP_FAMILY_7 is used or
IWL_FW_ERROR_DUMP_FAMILY_8 otherwise. This information is misleading and
incorrect since the driver sets the device family to 8 to any device that
is from family 8 and later, e.g. device family 9 is represented as 8 in
the dump.
Also, the device family enum is known only to the driver and
does not give any information to the FW developer

Change the device family to HW type to give propper data about the nic
in use.

In case the the trigger occurrences is zero or force_restart is set, the
driver sets IWL_FWRT_STATUS_DUMPING without actually scheduling trigger

Solve this by setting IWL_FWRT_STATUS_DUMPING bit only when the driver
is surely going to schedule dump collection

The driver calculates memory regions dump size, allocate memory and
fills the data.  The driver fills the radio registers data only if the
memory size of the fifos is greater then zero, so in case the user
masked out the fifos from the dump, the driver will skip filling the
radio register data.

Solve this by checking filling radio registers data independently from
fifos data.

In case of alive interrupt timeout or any failure in the init flow
the driver generates FW nmi. The driver assumes that the nmi will
generate SW interrupt. This assumption does not hold and leads to faulty
behavior in the recovery flow.

Solve this by using sync nmi, this way, even if the driver does not
receive SW interrupt, it still starts the recovery flow.

Also remove the wait queue from iwl_fwrt_stop_device since the driver is
handling the SW interrupt synchronously.

Trigger field ignore_default was changed to override_trig.
The first byte of the field indicates the driver to override existing
configuration or keep the previous one
The second byte of the field indicated the driver to replace the regions
of the previous trigger or to append new regions to it.

Change the way the active triggers are maintained to support trigger
override in different apply points.
Do this by making a trigger that updates at runtime by the
triggers that are being used in the different apply points.

In case of an assert, the driver does not reconfigure the triggers
and uses the old configuration which leads to undefined behavior.
Solve this by clearing the triggers in assert recovery flow.
