Blackfin arch: Fix bug using usb keyboard crashes kernel
Without conswitchp preset, we have the following situation:
- During initcalls: con_init is called, and returns because of
!display_desc.
- At this point there is no memory allocated for vc_cons[].d
A bit later vty_init calls kbd_init.
- From now on events are passed to kbd_event which will then call
kbd_keycode.
- kbd_keycode will oops on a NULL pointer dereference on vc->vc_tty
