Improve support of OpenGL for BeagleBone Black 



Make ti-gfx working on BeagleBone Black by adding an ugly necessary
patch to the kernel wich fix:
pvrsrvkm: Unknown symbol v7_dma_map_area
pvrsrvkm: Unknown symbol v7_dma_flush_range

Add drivers to the default kernel config used in beaglebone_defconfig
to enable the framebuffer.

Subject: [PATCH 3/3] arm: Export cache flush management symbols when

 !MULTI_CACHE



When compiling a kernel without CONFIG_MULTI_CACHE enabled the

dma access functions end up not being exported. Fix it.
