[PATCH v2 7/7] rockchip: add u-boot-rockchip-spi.bin image for booting from SPI-NOR flash

[Quentin Schulz <foss+uboot@0leil.net>]

From: Quentin Schulz <quentin.schulz@theobroma-systems.com>

This new image is similar to u-boot-rockchip.bin except that it's
destined to be flashed on SPI-NOR flashes.
