PATCH v2 1/2 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.

---
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
