brcm80211: fmac: move chip recognition function to sdio_chip.c
Currently backplane handle code is scatterd around dhd_sdio.c which is not good for maintenance and adding new backplane interconnect type support. This patch and the follow up patches are going to abstract all chip backplane control code specific for sdio bus into this new sdio_chip.c Reviewed-by: Arend van Spriel <arend@broadcom.com> Reviewed-by: Roland Vossen <rvossen@broadcom.com> Signed-off-by: Franky Lin <frankyl@broadcom.com> Signed-off-by: Arend van Spriel <arend@broadcom.com> Signed-off-by: John W.
