[media] media: rc: ir-sharp-decoder: add support for Denon variant of the protocol
Denon also uses the Sharp protocol, however with different check bits. It would have been also possible to add this as a separate protocol but this may not be worth the effort. Successfully tested with a Denon RC-1002 remote control. Signed-off-by: Heiner Kallweit <hkallweit1@gmail.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
