Fix several issues related to dump delay:
1. In legacy dump trigger, use stop_delay field instead of trig_dis_ms.
2. ini delay is messured in usec so align both ini and legacy to usec.
3. schedule_delayed_work receives the delay value in jiffies so
translate the dump delay to jiffies.

The FTM new API uses API TLV bit 15. The driver mistakenly uses
this bit for beacon filter API, although no TLV was assigned for
the beacon filter API. For now, make beacon filter use bit 16
instead (not set by the fw anyway). Once a TLV is assigned to the
beacon filter API it should be updated.

In low power modes, the chip clock source for platform integrated
devices is 32kHz. It is generated internally and supplied by a crystal
oscillator. However using a 32kHz sourced from crystal oscillator
has high power penalty.
There is an option to get an external 32kHz clock from the platform. Past
experience shows that the reliability is platform dependent,
i.e. on some platforms it works good and on other it doesn’t.
Working from external clock will save 0.5 mW in sleep state, from overall
1.8mW that we have today, i.e. almost 30%.
Each OEM can enable or disable the use of the external 32kHz clock by
setting a BIOS configuration. In case the OEM configured to use 32kHz
external clock the driver will pass this indication to the FW.

When flushing TX queues no new TX should go into the system.
However, in the following scenario we get TX:
1. Queues are stopped and there are packets in overflow queue
2. Station is removed and flush begins
3. Flush empties space, and reclaim path TXes SKB from overflow
queue.
Note that the fact the queues are stopped during the process
doesn't matter - the packet will be TXed since the TX path
doesn't care if TX queues are stopped or not, just if there is
space in the queue, which there is, since we just freed a
packet.
A fix here is rather complicated, since the flow is very racy.
Change code not to warn if we are TXing from overflow TX.
In case there is TX from both overflow TX and TX path we will
miss a warning we optimally had, but we can live with that.
Make sure we don't return before overflow queue is empty, otherwise
we will think queues are empty, but they will be refilled, resulting
with assert.

iwl_mvm_te_clear_data() is called for cleanup in case sending
the HOT_SPOT_CMD failed. However, in case sending the command
caused a fw error and restart (e.g. if the command is not supported)
then the te_data pointer may no longer be valid, which leads to
a NULL pointer dereference.
Fix it by checking that the te_data pointer is not NULL before
dereferencing it.

Add new API and TLV for the ability to send commands in the beginning
and end of reset flow.
The full flow of recovery is:
1. While loading FW, get address (from the TLV) of target buffer
to read in case of reset
2. If an error/assert happens read the address data from step 1.
3. Reset the HW and load the FW.
4. Send the data read in step 2.
5. Add station keys
6. Send notification to FW that reset flow is done.
The main use of the recovery flow is for support in PN/SN recovery
when offloaded

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.

Allocator swaps the pending requests with 0 when it starts
working. This means that relying on it n RX path to decide if
to move to emergency is not always a good idea, since it may
be zero, but there are still a lot of unallocated RBs in the
system. Change allocator to decrement the pending requests on
real time. It is more expensive since it accesses the atomic
variable more times, but it gives the RX path a better idea
of the system's status.
