563abc938f wifi: iwlwifi: use PNVM data embedded in .ucode files
Given compatibility issues with external PNVM data that doesn't match
the firmware it was designed with/for, future firmware releases will
include the PNVM data in the firmware files directly, avoiding those
mismatch issues. Make the driver load and use that embedded PNVM data
in preference of external files, falling back to the external file if
it isn't present.

3a68ae0fa2 wifi: iwlwifi: remove sku_id from trans
This is ephemeral data that's passed from the alive
response to the PNVM loading, so it doesn't need to
be stored. Pass it around instead.

31aeae2446 wifi: iwlwifi: cfg: remove trailing dash from FW_PRE constants
We have the trailing dash here, but that complicates all
the code. Simplify this by removing the dashes, adding
them to the *_MODULE_FIRMWARE macros, and adjusting the
code using this accordingly.

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:

5cc816ef9d iwlwifi: increase PNVM load timeout
The FW has a watchdog of 200ms in the PNVM load flow, so the driver
should have a slightly higher timeout.  Change the timeout from 100ms
to 250ms.
