Revert "force hardware graphics even if there's less than 512M ram present"

This reverts commit a8b6efcc3b28872b5a70894a938251fff9bafd23.

reverted because it causes system.ui to die with "invalid Bitmap format"
errors in android.opengl.GLUtils.texImage2D with some default CM wallpaper
images on non-default launchers (eg. apex).
also there was no noticable speed or functionality improvement with GL
forced to on.
patch: disable high dpi wallpapers to help shrink the rom size
