For SoCs with no GPU, configure weston to use the software versions
of egl and gles through mesa.

+# The 'egl' configuration of weston requires gles support, and consideration
+# must be taken for the different SoC capabilities:
+# - For SoCs with 3d support, imx-gpu-viv provides hardware-accelerated
+#   egl and gles, so weston egl configuration is enabled.
+# - For SoCs with VG2D, like i.MX 6SoloLite, imx-gpu-viv provides
+#   hardware-accelerated egl but does not provide a compatible software
+#   version of gles, so weston egl configuration is disabled.
+# - For SoCs with no GPU, mesa provides software implementations of egl
+#   and gles, so weston egl configuration is enabled.
