Geode platforms that use a LPC Super I/O had the LPC serial IRQ set to all

the possible IRQs generated by the SIO. This included IRQ 7 as the default
parallel port IRQ. This overlapped with the MFGPT driver setting IRQ7 for it's

that were setting it to prevent the conflict and crash when the MFGPT driver
loads.
