[U-Boot] [PATCH v2 1/2] ARM: at91sam9m10g45ek: enable mci0 support

[Josh Wu]

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.

v1 -> v2:
  1. refined the comment for the pins.
  2. remove detected pin initialization.
  3. move the mci initialization code to devices.c
  4. remove useless header file: mmc.h
