cdd30ebb1b module: Convert symbol namespace to string literal 
Clean up the existing export namespace code along the same lines of
commit 33def8498f ("treewide: Convert macro and uses of __section(foo)
to __section("foo")") and for the same reason, it is not desired for the
namespace argument to be a macro expansion itself.

bfc0ed73e0 Revert "wifi: iwlwifi: remove retry loops in start" 
Revert commit dfdfe4be18 ("wifi: iwlwifi: remove retry loops in
start"), it turns out that there's an issue with the PNVM load
notification from firmware not getting processed, that this patch
has been somewhat successfully papering over. Since this is being
reported, revert the loop removal for now.

We will later at least clean this up to only attempt to retry if
there was a timeout, but currently we don't even bubble up the
failure reason to the correct layer, only returning NULL.

dfdfe4be18 wifi: iwlwifi: remove retry loops in start 
There's either the pldr_sync case, in which case we didn't want
or do the retry loops anyway, or things will just continue to
fail. Remove the retry loop that was added in a previous attempt
to address the issue that was later (though still a bit broken)
addressed by the pldr_sync case.

3fd31289d5 wifi: iwlwifi: unify Bz/Gl device configurations 
All the configurations for the various Bz/Gl devices
are basically identical, except for Gl A-step and the
firmware filename prefixes.

Add some infrastructure to auto-generate the firmware
filename prefix based on the detected MAC step and
RF name/step, and remove all the unneeded configs.

This reduces the size of the iwlwifi module by ~9k:

5283dd677e iwlwifi: mvm: retry init flow if failed 
In some very rare cases the init flow may fail.  In many cases, this is
recoverable, so we can retry.  Implement a loop to retry two more times
after the first attempt failed.

This can happen in two different situations, namely during probe and
during mac80211 start.  For the first case, a simple loop is enough.
For the second case, we need to add a flag to prevent mac80211 from
trying to restart it as well, leaving full control with the driver.
