Further merge drivers by using the same command and data functions. No use one mutex per drive instead of a global sd lock. Fix the RCA handling which was different between SD and MMC (shifted 16) and thus confusing. Add MMC commands definition to the mmc.h header similarly to the SD one. Change MMC handling a bit by selecting/deselecting on each transfer like SD, which allows for several MMC devices in theory and is more uniform. Change-Id: I7024cb19c079553806138ead75b00640f1d2d95c
