Instead of directly passing NULL to the various irq_domain functions,
start by looking up the domain with a domain_token.
As domain_token is permanently set to NULL, the lookup function will
return the same value (no domain found) and the default will be used,
preserving the current behaviour.

Typo, should be irq_find_host() or
irq_find_matching_host(acpi_gsi_domain_token, DOMAIN_BUS_ANY),
it removed in later patch, so no compile error happened when
whole patch set applied.
Other than that,
