    mmc: sdhci: change sdhci-pltfm into a module · f0de8369

    There are a couple of problems left from the sdhci pltfm and OF
    consolidation changes.
    
    * When building more than one sdhci-pltfm based drivers in the same
      image, linker will give multiple definition error on the sdhci-pltfm
      helper functions.  For example right now, building sdhci-of-esdhc
      and sdhci-of-hlwd together is a valid combination from Kconfig view.
    
    * With the current build method, there is error with building the
      drivers as module, but module installation fails with modprobe.
    
    The patch fixes above problems by changing sdhci-pltfm into a module.
    To avoid EXPORT_SYMBOL on so many big endian IO accessors, it moves
    these accessors into sdhci-pltfm.h as the 'static inline' functions.
    As a result, sdhci.h needs to be included in sdhci-pltfm.h, and in
    turn can be removed from individual drivers which already include
    sdhci-pltfm.h.
