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.
