Yes. they're different chipsets.

In kernel priors to v3.13 the SDIO driver used generic firmware names.

Which makes me think that the non-versioned name was used by older drivers
for *all* chipsets, and you had to know what chipset you had to create the
right filename.  Modern kernels (post 3.13, January 2014 onwards) use
versioned firmware names so this is all redundant.
