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

[David Heidelberg via B4 Relay <devnull+david.ixit.cz@kernel.org>]

From: David Heidelberg <david@ixit.cz>

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.
