Add GEOM_RAID to GENERIC?

[John Baldwin]

I installed 9.0 on a new desktop that used Intel's on-board RAID yesterday and 
it worked great.  One nit though is I had to remember to kldload geom_raid 
manually from the shell before starting the install, and to load it from the 
loader on the first boot after install.  The old ataraid(4) was present in 
GENERIC, so I think it would be fine for GEOM_RAID to be present in GENERIC 
now (certainly on x86).  What do you think?
