Some platforms based on the shdci-pltfm device driver need to
set own quirks (that currently are in drivers/mmc/host/sdhci.h).
This patch splits this header file in two parts:
o drivers/mmc/host/sdhci.h
it includes the HC registers
o include/linux/mmc/sdhci.h
it includes the private structures, callbacks, quirks etc.
So, instead of including the shdci.h from devices/mmc/host, all
the platforms based on shdci-pltfm will be able to only include:
include/linux/mmc/sdhci.h and include/linux/sdhci-pltfm.h.
This has been tested on STM targets (STx7106, STx7108, STx5206).
Note: drivers/mmc/host/sdhci.h also includes the linux/mmc/sdhci.h
and no modifications should be needed on other sdhci-<XXX> drivers.
