    ssb: pick PCMCIA host code support from b43 driver · 399500da

    ssb bus can be found on various "host" devices like PCI/PCMCIA/SDIO.
    Every ssb bus contains cores AKA devices.
    The main idea is to have ssb driver scan/initialize bus and register
    ready-to-use cores. This way ssb drivers can operate on a single core
    mostly ignoring underlaying details.
    
    For some reason PCMCIA support was split between ssb and b43. We got
    PCMCIA host device probing in b43, then bus scanning in ssb and then
    wireless core probing back in b43. The truth is it's very unlikely we
    will ever see PCMCIA ssb device with no 802.11 core but I still don't
    see any advantage of the current architecture.
    
    With proposed change we get the same functionality with a simpler
    architecture, less Kconfig symbols, one killed EXPORT and hopefully
    cleaner b43. Since b43 supports both: ssb & bcma I prefer to keep ssb
    specific code in ssb driver.
    
    This mostly moves code from b43's pcmcia.c to bridge_pcmcia_80211.c. We
    already use similar solution with b43_pci_bridge.c. I didn't use "b43"
    in name of this new file as in theory any driver can operate on wireless
    core.
