[meta-fsl-arm][PATCH 2/4] xserver-xorg: Add bbappend to include dri and exclude glx for imx6

[Andrei Gherzan <andrei.gherzan@windriver.com>]

* Split glx PACKAGECONFIG flag in glx and dri. The one from oe-core includes
configs for dri and glx in the same PACKAGECONFIG[glx].
* There is no libgl in imx6 graphic libraries so don't compile xserver with glx.
* xserver driver for imx6 needs dri.h so compile xserver with dri for these
machines
