asahi: Allow no16 flag for disk cache

The debug flags are already plumbed into driver_flags for the disk
cache, so we just need to actually allow some flags instead of bailing
out of the disk cache init.

We only care about no16 for production right now, and it's probably a
good idea to disable disk caching during most debug sessions, so
allowlist only that one.
