[RFC PATCH 1/8] rockchip: generate idbloader.img content for u-boot-rockchip.bin with binman for ARM

[Quentin Schulz]

From: Quentin Schulz <quentin.schulz at theobroma-systems.com>

idbloader.img content - currently created by way of Makefile - can be
created by binman directly.

So let's do that for Rockchip ARM platforms.
