imx6q-sabresd: Add a qt5 defconfig variant

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.

[Arnout:
 - Add Fabio to DEVELOPERS
 - Rename linux config fragment to linux_qt5.fragment
 - Add comment to linux_qt5.fragment why it is needed
 - Add explicit CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE=y to it
 - Reorder defconfig entries to they match imx6q-sabresd_defconfig
 - Remove strace and host-uboot-tools, neither seems to be needed
 - Drop BR2_PACKAGE_QT5BASE_LICENSE_APPROVED, it no longer exists
 - Replace BR2_TARGET_ROOTFS_EXT2_BLOCKS with BR2_TARGET_ROOTFS_EXT2_SIZE
 - Regenerate .gitlab-ci.yml]

+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!
