### Contribution description

The offset of MTD regions must be aligned with erase sectors.
So in order not to waste address space, avoid misconfiguration and eventually support storage media > 4 GiB, give the offset in sectors instead of bytes.


### Testing procedure

`tests/mtd_mapper` should still work


### Issues/PRs references

in preparation of #14038
