iwlwifi: dbg_ini: remove periphery phy and aux regions handling
periphery phy and aux regions should not be collected like periphery mac
region. Remove their handling. The handling will be added in the future

iwlwifi: dbg_ini: use linked list to store debug TLVs
Use a linked list to maintain the debug TLVs instead of a single buffer.
This way, the driver does not need to iterate over the binary file twice
and allocates smaller chunks of memory. Also, in case one allocation
fails the driver will work with the partial configuration instead of
aborting the entire debug configuration.

This flag should never be set unless integration work with the
platform is done. We don't support any platforms officially and don't
plan to do so in the near future, so we can remove this option
entirely in order to avoid having it enabled by mistake.
This has been marked with "depends on EXPERT", so there shouldn't be
many systems running with it set. And, if there are systems, they
should not be using this flag.
For runtime PM to work with d0i3 code, a lot of integration work needs
to be done with the platform (e.g. the out-of-band wake up interrupt)
and we currently don't have any platforms where this integration
happened. So, this code has been pretty much stale for a while and
when someone enables it, it just breaks things.
Therefore, to simplify the code base and make sure no one enables this
by mistake, we will remove the whole code.
This is only the very start, much more work is needed.
Remove the places where we check iwl_mvm_is_d0i3_supported
but leave all the refs, those will be removed in a different
patch.

- Do not wait for a status report for the probe frame before removing the
probe rate from the rate table. Do it immediately after it was referenced
in a tx status report.
