[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.
