omap-a15: Add support for libgles and powervr drivers

* Add support for libgles and powervr drivers.
On OMAP5 and DRA7xx, the SGX 544MP2 is use. These patches enable support.
* There are significant differences between omap3-sgx/graphics-sdk recipes.
- There is no graphics SDK for OMAP5. Instead we have a DDK without any graphics demos. Separate recipes will be posted for demos.
- The PowerVR drivers are designed to be a omapdrm plugin. This is available separately as git tree from which we build the kernel module.
