reef/electro: modify keyboard scan rate
(from CL:415672) Slow the keyboard scan rate from 50 us to 80 us. This compensates the additional delay added to the KBO line by Silego / H1. BUG=chrome-os-partner:60335,chrome-os-partner:60615 BRANCH=reef TEST=check press key "f3" then system only output "f3" scan code.
