mb/google/poppy/variants/nautilus: Add SAR sensor device into devicetree.cb
This change defines SAR sensor device into devicetree.cb.
Since only LTE sku has SAR sensor, we will use GPP_B20 as a device_present_gpio.
BUG=None
BRANCH=poppy
TEST=Verified SAR sensor device is loaded by driver in Chrome OS
