description:
Don't call ukbd_cnattach() unconditionally, this causes a non-functionnal
keyboard if there is a framebuffer but the console is serial only.
Instead add a fdt_device_register_post_config() callback, which checks
if the just-attached wsdisplay is the console, and calls ukbd_cnattach()
in this case.
OK jmcneill@
