it8380dev: fix PWM moduel

Browse Source 
1. Fix fan turns on during sysjump if fan is disabled.
2. Remove unused board function.

Signed-off-by: Dino Li <dino.li@ite.com.tw>

BRANCH=none
BUG=none
TEST=1-1. Console 'sysjump RW' and fan keeps off.
     1-2. Console 'fanset 4000' or 'fanset 0' and 'sysjump',
          it dose maintain the fan RPM.
