sdmmc: actually implement mmc support - pass the correct ocr value for SEND_OP_COND (advertise Hcs and 3.3v) - disambiguate SEND_RELATIVE_ADDRESS/SET_RELATIVE_ADDRESS - detect the MMC version from CSD structure - detect the capacity according to spec for MMC - implement SWITCH command to set highspeed frequency and bus width - rename Ctlr to Card (thats really what we keep track of here)
