flashrom.c: implement chip restore callback registration
Allows drivers to register a callback function to reset the
chip state once programming has finished. This is used by
the s25f driver added in a later patch, which needs to change
the chip's sector layout to be able to write to the entire flash.
Adapted from cros flashrom at
