YoYo introduces 2 new region types: prph mac and phy blocks.
The data in this regions consists of a list of
(base address, size) pairs.
This way we can set a block of consecutive registers by the
base address and the size, instead of a list of registers.

In case the user sets the enable_ini to some preset, we want to honor

Remove the ops to set the value of the module parameter is runtime, we

There is a regular need in the kernel to provide a way to declare
having a dynamically sized set of trailing elements in a structure.
Kernel code should always use “flexible array members”[1] for these
cases. The older style of one-element or zero-length arrays should
no longer be used[2].

With more things being added, we're no longer going to duplicate
the error tables from the debug TLVs nor send them at runtime.

In firmware dumps, currently all kinds of key material may be
included, e.g. in host commands (if firmware crashes during the
processing of a key-related command) or in the TX FIFO(s) if
we have been using in-TX-command key material.
Additionally, some firmware versions will advertise sections
of their internal data to not dump, due to them containing some
sensitive data.
Add some infrastructure to allow scrubbing this data out, as
dependent on the opmode's idea of what will need to be done.

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.
