Samus: Fixed sensor init when sysjump to between RO and RW code

Browse Source 
When sysjump between RO and RW code, the motion sensor global
data structure get reset to 0.  The motion sensor task does not
get notification from the power state change event.

Added chipset S0 state check logic to re-init sensor active flag to S0.

BUG=chrome-os-partner:33370
BRANCH=ToT
TEST=sysjump RW; accelread 0
Test Cases:
  1 - press power cycle button; checked with powerinfo,accelread
  2 - press power cycle button + F3 (refresh) key; checked with powerinfo,accelread
  3 - Go to G3, S0, S3; checked with powerinfo, accelread
  4 - boot up to S0; sysjump RW; accelread 0|1|2
