mb/google/dedede/var/beadrix: Add a Proximity Sensor SX9324 for SAR

To meet LTE's RF Specific Absorption Rate (SAR) certification, we add a
Semtech Smart Proximity Sensor (P-Sensor) SX9324. P-Sensor connects
EC of I2C 5 bus and GPIO D22, D23, as well  as, SoC of GPIO E11, refer
to mainboard schematic.
