The presence or absence of a keyboard does not change whether an UART is designed as a keyboard port or not and thus whether we can use the port as a TTY or not. We now call sunkbd_attach() even when we didn't previously find a keyboard. Emit a useful message stating that no keyboard was found, but don't do anything else. MFC after: 5 days
