John Baldwin 030b156bf0 Add a simple mini-driver for the ELCR register. Originally, the ELCR 
register controlled the trigger mode and polarity of EISA interrupts.
However, it appears that most (all?) PCI systems use the ELCR to manage
the trigger mode and polarity of ISA interrupts as well since ISA IRQs used
to route PCI interrupts need to be level triggered with active low
polarity.  We check to see if the ELCR exists by sanity checking the value
we get back ensuring that IRQS 0 (8254), 1 (atkbd), 2 (the link from the
slave PIC), and 8 (RTC) are all clear indicating edge trigger and active
high polarity.

This mini-driver will be used by the atpic driver to manage the trigger and
polarity of ISA IRQs.  Also, the mptable parsing code will use this mini
driver rather than examining the ELCR directly.
