Damien George b6ab9e420b stm32/flash: Change flash_erase to only erase a single sector at a time. ...

An erase sector sits in a given flash bank and some MCUs have two flash
banks.  If trying to erase a range of sectors and that range crosses from
one flash bank into the next, the original implementation of
`flash_erase()` would not handle this case and would do the wrong thing.

This commit changes `flash_erase()` to only erase a single sector, which
sidesteps the need to handle flash-bank-crossing.  Most callers of this
function only need to erase a single sector anyway.
