Marek Vasut b5f403936d cmd: mmc: Add mmc reg read command for reading card registers
Add extension to the 'mmc' command to read out the card registers.
Currently, only the eMMC OCR/CID/CSD/EXTCSD/RCA/DSR register are
supported. A register value can either be displayed or read into
an environment variable.
