MFC 253392:
Workaround some broken BIOSes that specify edge-sensitive but active-low
settings for ACPI-enumerated serial ports by forcing any IRQs that use
an ISA IRQ value with these settings to active-high instead of active-low.

This is known to occur with the BIOS on an Intel D2500CCE motherboard.
