Subject: drm/etnaviv: select CMA and DMA_CMA if available
Git-commit: 63f5677544b3672979222fecef32c21e5131072b
Patch-mainline: v4.14-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

While this is no build dependency, etnaviv will only work correctly on most
systems if CMA and DMA_CMA are enabled. Select both options if available to
avoid users ending up with a non-working GPU due to a lacking kernel config.
