ARM: at91sam9m10g45ek: enable mci0 support
Also we enable the mmc command in configuration file. As both CONFIG_CMD_MMC and CONFIG_CMD_USB use the CONFIG_DOS_PARTITION, so remove the redundant CONFIG_DOS_PARTITION definition. Signed-off-by: Josh Wu <josh.wu@atmel.com> Signed-off-by: Andreas Bießmann <andreas.devel@googlemail.com>
