mb/google/dedede/var/drawcia: Add low_power_probe config for camera devices

Add low_power_probe config to camera devices so that driver skips initial
probe during kernel boot and hence prevents privacy LED blink.

BUG=b:178060668
TEST=Build and boot to OS on Drawcia. Ensure no blink on provacy LED.
