[PATCHv2 for v5.5] cec: CEC 2.0-only bcast messages were ignored

[Hans Verkuil]

Some messages are allowed to be a broadcast message in CEC 2.0
only, and should be ignored by CEC 1.4 devices.

Unfortunately, the check was wrong, causing such messages to be
marked as invalid under CEC 2.0.

Changes since v1:
- The second condition was wrong as well and allowed the broadcast command
  to be forwarded to CEC 1.4 adapters when it is a 2.0-only broadcast
  command.
