media: cec: move cec_register_cec_notifier to cec-notifier.h
The cec_register_cec_notifier function was in media/cec.h, but it has to be in cec-notifier.h. While we are at it, also document it and add a stub function for when the notifier is disabled or the CEC core code is unreachable. Based on an earlier patch from Jose Abreu <Jose.Abreu@synopsys.com>. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
