mb/google/nissa/var/craask: avoid camera LED blinking during boot
Camera LED will blink several times as sensor is being probed during kernel boot.
Configure _DSC to ACPI_DEVICE_SLEEP_D3_COLD so that driver skips
initial probe during kernel boot and prevent privacy LED blink.
BUG=b:274634319
TEST=Build and boot on Craask. Verify & observe Camera LED blinking behavior.
