Use correct abstraction for verify_range()

Browse Source 
The new abstraction can handle out-of-band chip communication protocols
as well. The old abstraction caused spurious false positives for erase
on SPI and spurious false negatives for verify on SPI.

Make verify_flash() use verify_range().

Tested by Uwe on SB600.

Corresponding to flashrom svn r629.
