Sometimes we want to read/write more than 4 bytes of chip content at once
Add chip_{read,write}n to the external flasher infrastructure which
read/write n bytes at once.
Fix a few places where the code used memcpy/memcmp although that is
strictly impossible with external flashers.
Place a FIXME in the layout.c code because usage is not totally clear
and needs to be fixed to support external flashers.
As a nice side benefit, we get a noticeable speedup for builtin flash
reading which is now a memcpy() of the full flash area instead of a
series of single-byte reads.
Corresponding to flashrom svn r579.
