mb/google/zork: restore stamp_boost parameter to 2500 for dirinboz 

Stamp_boost 1640 parameter is too short to keep APU performance.
Restore parameter to 2500 then APU could have longer boost time (~3xxx sec)

BUG=b:175364713
TEST=1. emerge-zork coreboot
     2. run balance performance and skin temperature test => pass
