When probed after the HDMI notifier, calling cec_notifier_cec_adap_register()
calls the enable() adapter callback, but the HW is not yet set up.
Moving cec_notifier_cec_adap_register() right before cec_register_adapter()
fixes the following crash:
Ignoring spurious kernel translation fault at virtual address 0000000000000008
