[PATCH 3/3] ARM: Rockchip: bbu: allow forcing barebox update handler despite size

[Ahmad Fatoum]

The update handler correctly refuses to write a bootloader when it would
interfere with partitioning.

Depending on use case, the user may want to override this check though,
so allow the barebox update force parameter to override it.
