[U-Boot] [PATCH v3 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.

Changes in v3: None
Changes in v2:
 - Add converting UART to support DM_SERIAL and used in the
