[Buildroot] [PATCH 1/1] configs: update config for Atmel SAMA5D3 Xplained board

[Ryan Barnett]

Update configuration to use the 3.18.8 kernel and update U-Boot to
2015.01. With the switch to 2015.01. use the U-Boot SPL image for the
first stage bootloader instead of the at91bootstrap. The U-Boot SPL
requires that the U-Boot image format be u-boot.img in order to load
from the SD card.

I've tested this on HW, and applied, thanks!

Now that there is a sama5d4 Xplained board, maybe we should rename this
defconfig, and the board directory to sama5d3-xplained or something
like that.

The sama5d4 Xplained real name is actually sama5d4 Xplained Ultra. That
would probably be different enough, unless Linux starts running on the
MCUs.
