[U-Boot] [PATCH v4 2/6] board: sama5d3xek: clean up code

[Wenyou Yang]

Due to the introduction of the pinctrl and clk driver, and using
device tree files, remove the unneeded hardcoded pin configuration
and clock enabling code from the board file.

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

Changes in v4:
 - Remove the ethernet init code completely.

Changes in v3: None
Changes in v2: None
