gpu-viv-bin-mx6q: bump to 5.0.11.p4.1

Bump the Vivante drivers to 5.0.11.p4.1. The version scheme has changed
and 5.0.11.p4.1 is indeed the latest version.

In addition to the version bump, other changes are done to handle the
new directory organisation.

Changelog:
- Package version is changed to use Vivante version
- imx-gpu-viv includes separate sub packages for demos and tools
  to support flexible package additions
- Graphics package is reorganized to improve library layout
- New GPU tool apitrace is added - supported only for X11 backend (not
  supported yet)
- gpu-viv-g2d shares same package with imx-gpu-viv (not supported yet)

This patch is based on the Yocto equivalent:

[Gary:
  1- used the pkgconfig files provided in the package from now on
  2- extend the commit log
  3 - add a symlink for libGAL_egl.so as it wasn't working on X
    - had to do a fixup as for some reason the lib is called libGAL_egl.dri.so
    Without that last symlink change, the tutorial examples were
    missing some symbols and qtbase wouldn't build.

This package has been tested with both X11 and Framebuffer backends;
 # cd /usr/share/examples/viv_samples/vdk/
 # ./tutorial7 ]
