mb/google/brya/var/kano: Prevent camera LED blinking during boot
Camera LED blinks as sensor is being probed during kernel boot, which misleads user to belive camera has been turned on. Configure _DSC to ACPI_DEVICE_SLEEP_D3_COLD so that driver skips initial probe during kernel boot and prevent privacy LED blink. BUG=b:214155527 TEST=Build and boot Kano to OS. Verify entries in SSDT and monitor LED during boot.
