Keep device name empty when the remote device does not report its osd

name

Previouly HDMI framework used a default name when a new hdmi cec device
is connected to the current devicei without reporting its osd name. But
this does not align with the produce requirement.

Current solution is to keep the name empty when notify device added to
the TV Input Framework. TIF handles this situation and takes the label
name of the service provided by the package manager instead. In this
case products can decide their own default name there.
