Replace remaining explicit erases in SPI programmer drivers with auto-erases
Some SPI chip drivers and the generic 1-byte SPI chip write functions didn't include the automatic erase present in other chip drivers. Since the majority is definitely auto-erase, change the remaining explicit-erase cases to be auto-erase as well. Corresponding to flashrom svn r673.
