PERFORCE change 170666 for review

http://p4web.freebsd.org/chv.cgi?CH=170666
 
Change 170666 by mav@mav_mavtest on 2009/11/16 13:51:06
 
	Disable PortMultiplier Async Notifications for time of ports reset.
	They are useless at that time, but confuse Marvell AHCI.
 
	Add quirk for SiI57XX Port Multipliers, to hide extra port.
