    mac80211: brcm: fix compilation warning for unused brcmf_of_fwnames
    
    If CPTCFG_BRCMFMAC_SDIO is not used brcmf_of_fwnames is defined but not
    used in the case of CONFIG_OF not compiled.
    
    Restrict brcmf_of_fwnames only with CPTCFG_BRCMFMAC_SDIO selected.
    Fix compilation warning:
