[Buildroot] [PATCH v3] imx6q-sabresd: Add a qt5 defconfig variant

[Fabio Estevam <festevam@gmail.com>]

Introduce imx6q-sabresd_qt5_defconfig that supports the opensource
Etnaviv graphical stack.

This defconfig provides a way to quickly test some graphical applications,
such as kmscube, qt5, glmark2.

Currently kernel mainline exhibits issues when running cpufreq as ondemand
governor on mx6, so add a linux fragment that disables such option for the
time being.

Changes since v2:
- Drop BR2_PACKAGE_MESA3D_DRI_DRIVER_SWRAST (Thomas)
- Bump to the latest kernel 4.11.6

+Testing graphics on the i.MX6Q Sabre SD board
+=============================================
+
+The imx6q-sabresd_qt5_defconfig allows to quickly test the graphics
+capabilities of i.MX6 using the opensource Etnaviv graphics stack
+and kernel mainline.
+
+In order to build it:
+
+make imx6q-sabresd_qt5_defconfig
+make
+
+Then flash the SD card as explained above.
+
+Running kmscube application:
+
+# kmscube -D /dev/dri/card1
+
+Running Qt5 Cinematic Demo:
+
+# export QT_QPA_EGLFS_KMS_CONFIG=/root/sabresd.json
+# /usr/share/Qt5/CinematicExperience/Qt5_CinematicExperience
+
 Enjoy!
