OpenBSD/OCTEON (partially) boots up from Compact Flash

We don't have complete kernel base software FPU emulation code, therefore userland is very unstable for now, but multi user mode booted from Compact Flash anyway.
I had tried to implement CF driver as wdc(4), looks like there's the way to do that if it's acceptable to patch few codes on the generic wdc(4) code, but I had got unknown hangs, and I gave up it.
Then I implemented simple block device "octcf", just like FreeBSD/cavium's CF driver.
