[PATCH] m68knommu: set irq priority/level different for each ColdFire serial port
Set the hardware interrupt priority to a different value for each
attached ColdFire serial port. According to the CPU documentation you
should not use the same combination of level/priority on more than one
device. People have reported odd serial port behavior with them set the
same.
