Move implicit erase out of chip drivers
Flashrom had an implicit erase-on-write for most flash chip and
programmer drivers, but it was not entirely consistent.
Some drivers had their own hand-rolled partial update functionality
which made handling partial updates from generic code impossible.
Move implicit erase out of chip drivers, and kill some dead erase
functions at the same time. A full chip erase is now performed in the
generic code for all flash chips on write, and after that the whole chip
is written.
Corresponding to flashrom svn r1206.
