Tatsumi Hosokawa 35e42bac95 Added "iosize" directive in /etc/pccard.conf
Allocate free I/O window with given size to card.

(example)
# IBM PCMCIA Ethernet I/II
card "IBM Corp." "Ethernet"
	config	0x1 "ed0" ?
	iosize	32
	ether	0xff0

(it's currently only useful for externalizing hacks for broken CIS cards,
 but it will play an important role with "function" directive I'm planninng
 to merge)

Reviewed by:	freebsd-mobile list
Obtained from:	PAO3's "cardio" directive
