ACPI: irq: Allow acpi_gsi_to_irq() to have an arch-specific fallback
It appears that the generic version of acpi_gsi_to_irq() doesn't
fallback to establishing a mapping if there is no pre-existing
one while the x86 version does.
While arm64 seems unaffected by it, LoongArch is relying on the x86
behaviour. In an effort to prevent new architectures from reinventing
the proverbial wheel, provide an optional callback that the arch code
can set to restore the x86 behaviour.
Hopefully we can eventually get rid of this in the future once
the expected behaviour has been clarified.
