If we have both, I think limiting to only one is by far the sanest option.
I'm not fully convinced by the need to have both, since the blocklist
allows wildcarding and exception cases. For example "net/[!i]*" will
blocklist all net drivers except those starting with an "i". Admittedly,
for usability purposes having an allowlist might work better.

One final thought, if we add a driver allowlist for cross files, should we
also add one as a top-level meson option also for consistency?
