arm64: dts: qcom: sm7325-nothing-spacewar: Add CAM fixed-regulators

Two regulators (GPIO 72 & 107) for the IMX766 sensor are missing here.
Without a driver, it's unclear if they're extra supplies or pwdn/power
GPIOs (labeled "custom" in the downstream kernel).

So add only those fixed regulators that are currently predictable for
camera sensors, camera EEPROMs and camera actuators.
