The ti-vxe-vxd-driver (out of tree module) requires the VIDEOBUF2_DMA_SG module to be built. But the in layer defconfig is pruning several options from the default defconfig that prevents us from easily turning it back on. This KERNEL_CONFIG_FRAGMENTS entry will turn on all of the needed options to re-enable the VIDEOBUF2_DMA_SG setting.
This might be a temporary fix as there is effort to move the ti-vxe-vxd-driver back into the kernel tree which will clean up the Kconfig mess that requires this fragment.
