[Buildroot] [PATCH v8 2/3] boot/uboot: Add support for Rockchip binary blobs

[Kilian Zinnecker]

Currently for some Rockchip SoCs binary blobs are needed, e.g., for
the RK3588 bl31 and tpl. These blobs are provided by Rockchip. This
patch adds U-Boot package options to use theses binaries, provided
by the rockchip-rkbin package, which is also introduced in this
patch series. The U-Boot package is modified so that it takes the
chosen binaries and automatically uses them during build.
