Add a pass-through ioctl for mfi(4), allowing userland to send raw commands
to the controller. This is compatible with the linux and FreeBSD
implementations.
Add the needed conversion for mfi ioctls in COMPAT_LINUX
Allocate a character major number, and create /dev/mfi0 by default
on amd64 and i386.
This allows (along with a hand-created /emul/linux/proc/devices file)
to run the MegaCLI linux binary provided by LSI.
