[U-Boot] [PATCH v4 1/3] configs: at91sam9rlek: Update for DT and DM support

Tue Apr 18 07:28:27 UTC 2017

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.

Changes in v4:
 - Adjust CONFIG_ENV_OFFSET for NAND to avoid the conflict caused
   by the increased binary size.

Changes in v3: None
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.
