[PATCH 6/6] rockchip: mkimage: Add option for image load address and flag

[Jonas Karlman]

The v2 image format supports defining a load address and flag for each
embedded image.

Add initial support for writing the image load address and flag to the
v2 image format header.

This may later be used for RK3576 to embed a minimal initial image that
if required to fix booting from SD-card due to a BootROM issue.
