mmc: CMD7:MMC_CMD_SELECT_CARD response fix
As per JEDEC document JESD84-A441 (page 105) response for CMD7 (MMC_CMD_SELECT_CARD) response should be R1 instead of R1b. In uboot we never take MMC to disconnected state and on powerup its always ideal state which later goes to stand-by state. from document footnote: R1 while selecting from Stand-By State to Transfer State; R1b while selecting from Disconnected State to Programming State.
