imx-base: Include gstreamer1.0-plugins-imx for i.MX6Q and i.MX6DL

gstreamer1.0-plugins-imx can only be used with i.MX6Q and i.MX6DL
(instead of any i.MX6) as the others does not provide a VPU. This
commit updates the default setting accordingly.

piglit: Add a dependency over virtual/egl

The build system can also use egl when GL is not avail so we ought to
add this to the dependency chain as gpu-viv-bin-mx6q would not be
included otherwise, for i.MX6SL.

chromium-imx: Update chromium-imx to support SOC without VPU

Current VPU patches only work for mx6q and mx6dl that have VPU.  To build for future mx6sx need
to split VPU patches off for only mx6q and mx6dl. Also depends on libfslvpuwrap should be
restricted to mx6q and mx6dl.
