[U-Boot] [PATCH v2 1/3] configs: at91sam9m10g45ek: Update to support DM/DT

[Wenyou Yang]

Update the configuration files to support the device tree and driver
model. The device clock and pins configuration are handled by the
clock and the pinctrl drivers respectively.

Because the limitation of internal SRAM size, the SPL with driver
model can't be supported, disable the SPL option.

Signed-off-by: Wenyou Yang <wenyou.yang at atmel.com>

Changes in v2:
 - Add the support of Atmel uart device be used in the
   board_init_f stage.
 - Remove unused LED feature.
 - Disable the SPL options.
