X-Git-Tag: v4.14-rc1~179^2~21^2~3

drm/etnaviv: select CMA and DMA_CMA if available

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.
