Flashrom does not honor argument ordering for operations

Not only does this violate the principle of least surprise, it also
caused one bug where -Ewv was specified and the flash ended up being
empty.

Support only one operation at a time. As a side benefit, this allows us
to clean up main() quite a bit.

Corresponding to flashrom svn r585.
