lynxpoint: Enable extra 16 IOAPIC entries for GPIO PIRQ

LynxPoint-LP has an additional 16 entries in the IOAPIC that
    can be assigned to specific GPIOs when they are configured
    as PIRQ.

The maximum redirection entries field in the IOAPIC needs to
    be set to 0x27 when this is enabled.

Additionally specific GPIOs need to be routed to PIRQ so they
    interrupt via the IOAPIC instead of the GPIO IRQ 14/15.
