support variable-size SPI chip for dummy programmer
This is designed for firmware updater to pack firmware image
preserving some specific partitions in any size.
BUG=none
TEST=ran the command line below:
$ flashrom -p dummy:image=${TMP_FILE},size=16777216, \
emulate=VARIABLE_SIZE -w ${IMG} -V -f
$ flashrom -p dummy:image=${TMP_FILE},size=auto, \
emulate=VARIABLE_SIZE -w ${IMG} -V -f
