[media] media: rc: ir-sharp-decoder: add support for Denon variant of the protocol

Browse Source 
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.
