[U-Boot] [PATCH v3 02/16] rockchip: move bootrom helper compilation to a hidden option

[Heiko Stuebner]

Right now the ROCKCHIP_SPL_BACK_TO_BROM option both triggers
compilation of the bootrom hook-code as well as enabling the
behaviour of loading the full uboot via the boot.

New added socs may always need the bootrom code, while still
being able to decide between loading uboot regularly or via
the bootrom separately.

So move the compilation of the bootrom code to a hidden option
that gets selected by ROCKCHIP_SPL_BACK_TO_BROM, but can also
be selected by other parts.

           SPL will return to the boot rom, which will then load the U-Boot
