external/pflash: Correct erase alignment checks

pflash should check the alignment of addresses and sizes when asked to
erase. There are two possibilities:
1. The user has specified sizes manually in which case pflash should
be as flexible as possible, blocklevel_smart_erase() permits this. To
prevent possible mistakes pflash will require --force to perform a
manual erase of unaligned sizes.
2. The user used -P to specify a partition, partitions aren't
necessarily erase granule aligned anymore, blocklevel_smart_erase() can
handle. In this it doesn't make sense to warn/error about misalignment
since the misalignment is inherent to the FFS partition and not really
user input.
