wimax/i2400m: correctly identify all iwmc3200-based SKUs

Different paths of the i2400m SDIO driver need to take care of a few
SKU-specific quirks. For the ones that are common to to all the
iwmc3200 based devices, introduce i2400ms->iwmc3200 [set in
i2400ms_probe()], so it doesn't have to check against the list of
iwmc3200 SKU IDs on each quirk site.
