amlogic refactoring

[redPanther]

1. Tell us something about your changes.

• all grabbers switch auto off when not active prio
• aml grabber switch automatically between best available grabber - no 2 active grabbers on aml platform anymore
• structural preparations for aml grabber to use GE2D directly (https://forum.odroid.com/viewtopic.php?f=136&t=20901)
• standalone grabber hyperion-aml now captures accelerated and not accelerated video. before only accelerated video was possible

I'm working on support for a new direct capturing interface for so called ge2d. Currently I'm getting the video into hyperion, but I have problems to decode it. see here for more https://forum.odroid.com/viewtopic.php?f=136&t=20901

2. If this changes affect the .conf file. Please provide the changed section

3. Reference an issue (optional)

Note: For further discussions use our forum: forum.hyperion-project.org

I'm happy to announce I can use/test amvideocap now and it works smoothly with hyperion. Next step will be to support ge2d direct capturing (with a special kernel patch).
