Because I got big trouble while testing TCP/UDP cksum offload
fix for hme(4) on console, I touched ofw_console code. I stole
the code from OpenBSD. It seems that now the console works as
expected. No more 1 sec. pause needed to see correct typing on
keyboard. Here is patch. I'm not familiar with tty code, so
it may be just dirty hack or it may not work except my Ultra2.
