Update the Rockchip documentation for image generation with binman, including the new automatically-created SPI image.
Signed-off-by: Andrew Abbott andrew@mirx.dev ---
Changes in v2: - Remove note from docs about different offsets in SPI flash for different SoCs - this was a bad assumption on my part, it doesn't work this way. - Update name of SD/MMC image in the docs from u-boot-rockchip-sdmmc.bin to u-boot-rockchip.bin.
