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.
