Add info about bus width of the attached card to the bring-up message For both MMC and SD cards the bus width that is used might not be obvious to a user. For MMC this might be 1, 4 or 8, for SD only 1 and 4. In both cases this would be a restriction by the host (setup). Like using an MMC in an SD slot or an eMMC to SD adapter.
