mb/google/poppy/variant/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
