The new firmware code tries to re-read the formerly read firmware files before suspend. Thus it's wiser to keep the "patch" firmware in the driver for avoiding this unnecessary re-reading.
Of course, this will consume a bit of memory for unused stuff, but the patch fw is supposed to be fairly small, so it's more benefit in the end.
