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
own use. This fix removes IRQ7 from the serial IRQ list for all the mainboards
that were setting it to prevent the conflict and crash when the MFGPT driver
loads.
