arm: at91: Add gardena-gateway-at91sam support

The GARDENA smart Gateway boards are equipped with an Atmel / Microchip
AT91SAM9G25 SoC and with 128 MiB of RAM and 256 MiB of NAND storage.
This patch adds support for this board including SPL support. Therefore
the AT91Boostrap is not needed on this platform any more.
