arm64: dts: rockchip: Add light/proximity sensor to Pinephone Pro

Browse Source 
Pinephone Pro uses STK3311 according to the schematics.

Tests:
~ $ monitor-sensor --light
    // When the sensor is exposed, it get's fluctating values such as
    Light changed: 1.800000 (lux)
    Light changed: 1.700000 (lux)
    Light changed: 1.800000 (lux)
    Light changed: 1.700000 (lux)
    Light changed: 1.600000 (lux)
    Light changed: 1.100000 (lux)
    // When covering the sensor, it prints a low value and stops printing
    Light changed: 0.200000 (lux)

~ $ monitor-sensor --proximity
    // When it goes away from an object
    Proximity value changed: 0
    // When it comes near an object
    Proximity value changed: 1
