Different baseboards may shuffle around the eMMC/SD aliases differently
and thus the barebox update handler registration may not be correct
across all of them.
Instead of hardcoding the eMMC device and SD device, let's derive the
correct index dynamically at runtime using the mapping that the barebox
bootsource code is already using.

Jonas, can you give this a test and see if it works for you?
