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.
