Hans Verkuil 812765cd69 media: vivid: add <Vendor Command With ID> support
This makes it possible to test the new CEC_MSG_FL_REPLY_VENDOR_ID flag.

The vivid driver will Feature Abort any messages that do not have
exactly 1 payload byte. It ignores messages where the payload byte is
even, and where it is odd it will reply with the payload byte incremented
by 1. Basically a simple ping-pong command.
