x86: update mptable fix with no ioapic v2
if the system doesn't have ioapic, we don't need to store entries for mptable update also let mp_config_acpi_gsi not call func in mpparse so later could decouple mpparse with acpi more easily Reported-by: Daniel Exner <dex@dragonslave.de> Signed-off-by: Yinghai Lu <yhlu.kernel@gmail.com> Cc: Andrew Morton <akpm@linux-foundation.org> Cc: Daniel Exner <dex@dragonslave.de> Cc: Len Brown <lenb@kernel.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>
