mb/google/brya/var/redrix: Configure _DSC for CAM devices to ACPI_DEVICE_SLEEP_D3_COLD
Configure _DSC to ACPI_DEVICE_SLEEP_D3_COLD so that driver skips initial probe during kernel boot and prevent privacy LED blink. BUG=b:199823938 TEST=Build and boot redrix to OS. Verify entries in SSDT and monitor LED during boot.
