mb/google/nissa/var/yavilla: avoid mipi camera LED blinking during launch
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:292173903
TEST=Build and boot on Yavilly EVT unit. Verify & observe Camera LED
blinking behavior.
