drm/nouveau/secboot: support optional falcons

Browse source

PMU support has been enabled for r352 ACR, but it must remain optional
if we want to preserve existing user-space that do not include it. Allow
ACR to be instanciated with a list of optional LS falcons, that will not
produce a fatal error if their firmware is not loaded. Also change the
secure boot bootstrap logic to be able to fall back to legacy behavior
if it turns out the boot falcon's LS firmware cannot be loaded.
