cnss2: Update the wlan fw name for Genoa

Since PCIE Genoa has separate wlan fw patch for
mission mode(amss.bin) and ftm mode(genoaftm.bin),
but cnss2 platform driver always try to load amss.bin,
which is not feasible. So add this new interface for
cnss2 to get correct driver mode and update the fw
patch name.
