[PATCH net-next] brcmfmac: fix build without CONFIG_BRCMFMAC_PROTO_BCDC




With CONFIG_BRCMFMAC_PROTO_BCDC unset, we cannot build the fwsignal.c file:

drivers/net/wireless/broadcom/brcm80211/brcmfmac/fwsignal.c: In function 'brcmf_fws_notify_credit_map':
drivers/net/wireless/broadcom/brcm80211/brcmfmac/fwsignal.c:1590:31: error: implicit declaration of function 'drvr_to_fws'; did you mean 'dev_to_psd'? [-Werror=implicit-function-declaration]
  struct brcmf_fws_info *fws = drvr_to_fws(ifp->drvr);
drivers/net/wireless/broadcom/brcm80211/brcmfmac/fwsignal.c:1590:31: error: initialization makes pointer from integer without a cast [-Werror=int-conversion]
drivers/net/wireless/broadcom/brcm80211/brcmfmac/fwsignal.c:1621:31: error: initialization makes pointer from integer without a cast [-Werror=int-conversion]

However, as pointed out in the changeset description for the patch that caused
the problem, fwsignal.c is only required when CONFIG_BRCMFMAC_PROTO_BCDC is
enabled, so we can simply change the Makefile to build it conditionally.
