Add the version number to the iwl_geo_tx_power_profile_cmd structs and
move the union into a common place. Additionally, reuse the code that
sets elements that are at the same place in the struct across
different versions.
While at it remove an unused variable, add a comment and move the v2
specific element setting to inside the if statement. Additionally,
invert the if for slightly more readability.

The new version of the command can support more subbands and CDB, so
it can contain more data than earlier versions. Implement support for

Create a common structure to contain all different versions of the
tx_power_cmd instead of making a union of the different structs
everywhere we need them. Also move the common part of these structs
into a separate structure (instead of reusing v3) and leave the
per_chain_restriction part out of the common part, because this will
change in version 6 of the command (which will be added soon).
While at it, rename per_chain_restriction to per_chain to shorten it.

On newer hardware, we have the full checksum, so use it to report
CHECKSUM_COMPLETE and avoid the protocol specific hardware parsing.
Note that the hardware already parses/removes the SNAP header, so
we actually literally get what we need to report to the stack, as
we're expected to checksum everything after the L2 header (which
is translated/added by mac80211).

The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:
struct foo {
int stuff;
struct boo array[];
};
By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.
Also, notice that, dynamic memory allocations won't be affected by
this change:
"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]
sizeof(flexible-array-member) triggers a warning because flexible array
members have incomplete type[1]. There are some instances of code in
which the sizeof operator is being incorrectly/erroneously applied to
zero-length arrays and the result is zero. Such instances may be hiding
some bugs. So, this work (flexible-array member conversions) will also
help to get completely rid of those sorts of issues.
This issue was found with the help of Coccinelle.

There are several "flavors" of HW that have the same HW type, but
can be told apart after reading a certain perph register. This
is easy to do in runtime, but more complicated to do when looking
at the logs offline.
To make it easier to tell apart these "flavors" when looking at
the dumped dbg info, add these bits to the HW type, allowing

Due to some hardware issues, queue 31 isn't usable on devices that have
32 queues (7000, 8000, 9000 families), which is correctly reflected in
the configuration and TX queue initialization.
However, the firmware API and queue allocation code assumes that there
are 32 queues, and if something actually attempts to use #31 this leads
to a NULL-pointer dereference since it's not allocated.
Fix this by limiting to 31 in the IWL_MVM_DQA_MAX_DATA_QUEUE, and also
add some code to catch this earlier in the future, if the configuration
changes perhaps.
