[PATCH v2 0/3] rockchip: remove u-boot.rom generation and use binaries from simple-bin in simple-bin-spi image

[Quentin Schulz]

This gets rid of u-boot.rom generation as that was used only on Rockchip
Chromebooks and their maintainer (Simon) seems to agree[1] that
u-boot-rockchip-spi.bin should do the job now so we don't need to
generate it anymore. This was agreed for RK3399 Chromebooks, I'm
attempting to do the same for RK3288 Chromebooks as well so we don't
have anything requiring that u-boot.rom anymore.

Since HAS_ROM is only guarding this u-boot.rom generation, they are
removed too from the individual configs.

Finally, this also fixes an issue reported by Naoki[2] where binman
would try to find symbols from proper to install in xPL binary only for
it to not find it as we do not generate (on Aarch64) the proper binary
in simple-bin-spi image node, only in simple-bin, so it cannot have
access to the symbol. As to why this triggered only when some seemingly
unrelated symbols are enabled, I do not know.

The first two commits are cleanups. If they are controversial, they can
be dropped and I'll apply the same fixes for rockchip-u-boot.dtsi to
{rk3288,rk3399}-u-boot.dtsi binman nodes.

Note that none of the patches were tested outside of a simple build
test.

Changes in v2:
- made u-boot-rockchip-spi.bin 8MiB for RK3399 Chromebooks and 4MiB for
  RK3288 Chromebooks, as requested by Simon, to match u-boot.rom,
- added R-b from Jonas,
- surrounded &/binman/simple-bin-spi in chromebook dtsis with ifdefery
  on ROCKCHIP_SPI_IMAGE to not pollute the Device Tree if it's not
  there,
