Use build property for CEC device OSD name

Previously OSD name was based on device type. This CL makes it
independent of device type. CEC spec says "A device that implements
more than one type of CEC functionality should respond with the same
OSD name for each logical address. It is recommended that the name
refers to the complete physical product rather than the individual
CEC functionality".

Now the default name comes from system build property. I removed
setOsdName() from aidl for now since it won't be in use.
