media: include/uapi/linux/cec*: clarify which msgs are CEC 2.0

Drop comments about CEC 2.0 from cec-funcs.h.

In cec.h clearly comment messages that are CEC 2.0 specific
as such. Also rename references to HDMI 2.0 to CEC 2.0.

The <Request/Report Current Latency> messages were marked
as CEC 2.0 only. That is wrong, these messages are explicitly
allowed for any CEC version.
