Update the Rockchip documentation for image generation with binman,
including the new automatically-created SPI image.
Signed-off-by: Andrew Abbott <and...@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.
