[PATCH v4 8/8] rockchip: add u-boot-rockchip-spi.bin image for booting from SPI-NOR flash

[Quentin Schulz]

From: Quentin Schulz <quentin.schulz at 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.

v3:
 - added filename property so that idblaoder-spi.img binary is generated
 by binman, as per community request,
 - added new temporary files to the list of files to clean up on `make
 clean`,
