pbody:disable PP3300_DX_TRACKPAD in S3
when enter S3, set ENABLE_TOUCHPAD low to reset, then return S0,
set ENABLE_TOUCHPAD to high.
BUG=b:35647991
BRANCH=firmware-glados-7820.B
TEST=build and burn on pbody
1. enter S3,run "gpioget" on EC console, check ENABLE_TOUCHPAD is low.
2. return to S0, ENABLE_TOUCHPAD is high now, and keyboard can be used.
