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.

identical.

Some chips implement the RES (0xab) opcode, but they use a non-standard
two byte response instead of the usual one byte response. A two-byte
response has the accuracy of REMS and RDID, so don't check for REMS/RDID
availability before running a two-byte RES.
