Add writeback support to modetest with the below options:
- Passing in -a -c will now also show the writeback connector
- Dump the writeback output buffer to bitstream
Usage: "./modetest -M msm -s <connector_id>:<widthxheight>
-a -o <filepath>
-P <plane_id>@<crtc_id>:<widthxheight>+0+0@RG24"
This currently supports single writeback connector.
