Introduce two new tunables from the boot loader.

hw.pcic.irq		Globally set the IRQ for all pcic devices' management
			interrupt (aka card status change or CSC interrupt)
			This is what used to be known as
			machdep.pccard.pcic_irq (which has been retained for
			now for compatibility).
hw.pcic.ignore_fuction_1 Ignores function 1 for all PCIC bridges by not
			attaching to them.  Lucent released a huge batch
			of cards that were imporperly manufactuered (lacking
			the 0 ohm resister to disable slot 1).  This is
			a big hammer to keep those cards from causing problems
			(I've had 4 people contact me saying my patches
			worked great once they added a kludge to always ignore
			function 1, or until they soldered these resistors
			in place!).

No clue where to document these.  They act as both boot loader environment
variables, as well as read-only sysctls after boot.

At the same time, sort sys/systm.h in its proper order after sys/sysctl.h.
