[PATCH v3 4/8] rockchip: generate idbloader.img content for u-boot-rockchip.bin with binman for ARM

[Quentin Schulz <foss+uboot@0leil.net>]

From: Quentin Schulz <quentin.schulz@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.

v3:
 - moved spl back into mkimage section,
 - added filename property so that the idbloader.img binary is still
 generated,
