Child device 0x2 used to be "TV" until redefined to mean
EFP5 in version 215. Add a define for the old meaning as well.

Technically it was probably deprecated a lot before version
215 since native TV encoders were last seen on CTG, and SDVO
was fully gone by HSW. So something like "???-164" might also
be a reasonable way to document this, but no real harm in
saying "???-214" since nothing else presumably occupied that
bit in the meantime.
