Add a bus_add_child device method to bcm2835_sdhci.

Browse Source 
This allows SDIO (through CAM) to attach to an upstream, e.g.,
      ..
      sdhci_bcm0 pnpinfo name=mmc@7e300000 compat=brcm,bcm2835-mmc
        sdiob0
          ..

Without this, upon trying to load sdio, we would panic with
"bus_add_child is not implemented".
