redPanther 2aa4df92a9 amlogic refactoring (#464)
* - grabber auto off when not set as active prio
- join aml and fb - on aml platform both grabbers are needed, so they joind in one module and share one prio. user don't the the nasty magic behind
- aml: preparation for direct ge2d access

* just save it, in the middle of ge2d impl

* fix compile issues

* now grabbing works basicly

* add 3d support for ge2d

* next step, we got some video from aml

* switch back to rgba

* remove unfinished ge2d stuff

* commit missing changes

* some urgent fixes, needs some beautifying, but it works now

* fixes and refctoring
