mb/google/zork: update stamp_boost parameter for gumboz
Original Stamp_boost parameter will cause boost time over 2500sec(3960sec)
To pass balance performance and skin temperature test, decrease stamp_boost:
2500 -> 1640
BUG=b:182753072
TEST=1. emerge-zork coreboot
2. run balance performance and skin temperature test
