[meta-intel] Do we still need GST_API_VERSION inside gstreamer-vaapi-xxx.bb recipes?

[Lim, Siew Hoon]

>> Gstreamer-vaapi already include those GST_API_VERSION checking in configuration.ac which gstreamer framework version support.
>> And --with-gstreamer-api option also didn't exist in gstreamer-vaapi.

>> Will get this kind of warning message:
>> WARNING: QA Issue: gstreamer-vaapi-1.0: configure was passed unrecognised options: --with-gstreamer-api [unknown-configure-option]


>> Can we do a cleanup for it?
>> 1. Remove out --with-gstreamer-api=${GST_API_VERSION} inside the gstreamer-vaapi.inc?
>> 2. Remove out the GST_API_VERSION from gstreamer-vaapi recipes?

>It was needed in the past when there were both 0.10 and 1.0 recipes for gstreamer-vaapi, but if gstreamer-vaapi has removed the --with-gstreamer-api option then it can all be deleted.

Run configuration: ./configure or ./autogen.sh --prefix=/usr 
Got warning message: configure: WARNING: unrecognized options: --with-gstreamer-api 

But I just found out in gstreamer-vaapi/debian.upstream/rules file, got this --with-gstreamer-api=$(GST_API_VERSION).
Will check whether gstreamer-vaapi side missing this out clean up in gstreamer-vaapi/debian.upstream/rules as well.

OK. Then I will go double check and confirm before create a patch for this one to do clean up.

Thanks.
