core/flash-subpartition: compute partition size from subpartition struct
From the subpartition structure, we have the ability to compute
the full partition size. Do that.
This lets us only read the amount of a subpartition that is valid
and needed to be read, rather than having to read the entire thing.
We continue the current behaviour of loading flash partitions though.
