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.

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:

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.
