[U-Boot] [PATCH v2 1/3] configs: at91sam9rlek: Update for DT and DM support

[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.

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

Changes in v2:
 - Add converting UART to support DM_SERIAL and used in the
   board_init_f stage.
 - Remove unused LED feature.
 - Improve the commit log.
