ARM: dts: msm: remove actuator probe during bootup to avoid latency issue

The 8909w doesn't have actuator in the camera modules, so no actuator
device tree should be configured in device tree.
The actuator probe process will also add some time in bootup and control
the power supply, so remove the actuator config in 8909w.
