mb/purism/librem_mini: Implement `die_notify`
Make the SATA LED blink when coreboot dies. GPIO functions aren't
compiled in for postcar, so add a check to prevent linker failures.
TEST: Try to boot Librem Mini WHL without RAM, observe blinking (and
also blinding LED). Re-install RAM (and re-seat RAM a few times),
boot to OS, and observe SATA LED operating normally, as expected.
