[PATCH] Moving CAM config to private SYSINIT

All,

I'm working on fixing the boot-from-USB-doesn't-always work problem,  
which turns out to be a race between several different threads at  
boot.  As a pre-requisite to controlling the race, I'm moving the CAM  
bus/device scan to its own private SYSINIT so that its execution is  
ordered.  In practice, it should not affect anything, and systems  
should continue to boot as normal.  That's where I need help in  
testing.  If you have any CAM/SCSI devices that are present when you  
boot, please test this patch and let me know if it changes anything  
for you, good or bad.
