mainboard/google/poppy: Configure GPIO.1 and GPIO.2 for daisy chain mode
Configure GPIO.1 and GPIO.2 as sensor SDA and SCL respectively
for TPS68470 PMIC in daisy chain mode.
* GPIO.1: Sensor SDA in daisy chain mode.
* GPIO.2: Sensor SCL in daisy chain mode.
BUG=b:38326541
BRANCH=none
TEST=Build and boot soraka. Dump and verify that the generated DSDT table
has the required entries. Verified that sensor probe is successful.
