common/flash.c: Rename flashwp parameter from [no]rw to [no]all

Saying that 'flashwp rw' was protecting RW region was not really
accurate: it was actually protecting the whole flash (which,
well, is actually equivalent as the RW can't be protected without
the RO).

Let's fix that in anticipation for adding a new flag that will
_really_ set the RW protection (and only that).
