enhancing module info to allow grouping of firmwares

Hey moduly/firmware people,

We are facing a problem in the future of NVIDIA providing giant
firmwares for their devices that are version locked with unstable
APIs. Even if they weren't version locked we'd likely have to support
multiple major versions over time.

Now this becomes a problem because when you generate multiple
initramfs and stick them into /boot over time the number of firmwares
MODULE_FIRMWARE will match will increase and dracut will shove them
all into the initramfs.

I think one way to mitigate that would be to provide some sort of
grouping of module firmwares that are acceptable, and having dracut
only pick one from the list to provide in the initramfs (hopefully the
latest one). That way the driver can provide a list of MODULE_FIRMWARE
lines and userspace knows they are a group.

I've just little idea how we could expose this via current module
info, happy to try and come up with an enhanced scheme maybe with a
fallback to just include all of them but was just wanting to get some
feedback on whether this was something that anyone has ever considered
before now.

Thanks,
Dave.
