We extend V4L2 capabilities and V4L2_M2M functionality.

Summary

• Added many V4L2 standard definitions
• Expanded some driver ops content and enhanced framework level inspection capabilities.
• Unified use of v4l2_buffer.vaddr field with driver to interact with actual memory address.
• Add support for mplane and userptr memory.

Impact

• The way the codec dirver interacts with m2m for data memory addresses has been changed from v4l2-buffer.userptr to v4l2-buffer-vaddr. We believe that changing the semantics in this way is more obvious.
• All other changes are incremental functional modifications and will not introduce compatibility issues.

Testing

Tested in Simulator environment and passed
