Flash mapping/unmapping was performed without an abstraction layer, so even the dummy flasher caused memory mappings to be set up
Add map/unmap functions to the external flasher abstraction. Fix a possible
scribble-over-low-memory corner case which fortunately never triggered so far.
With this patch,--programmer dummy works fine as non-root.
Corresponding to flashrom svn r493.
