[PATCH v3 2/2] arm64: dts: qcom: sdm845-shift-axolotl: Add actuator for main rear camera

Main rear camera uses Dongwoon DW9714V actuator. Add regulator and
actuator node.

Since the actuator sits on the CCI I2C bus, whose 1.8V side is fed by
vreg_lvs1a_1p8 and there is no place to describe that, keep it always-on
for now, until bus-supply exists.
