x86, irq: don't call mp_config_acpi_gsi() if update_mptable is not enabled
Len expressed concern that the update_mptable feature has
side-effects on the ACPI code.
Make it sure explicitly that the code only ever gets called if
the (default disabled) update_mptable boot quirk option is
disabled.
[ Impact: isolate the update_mptable feature from ACPI code more ]
