[PATCH v2 3/3] drm/etnaviv: use a 32 bit mask as coherent DMA mask

The STLB and the first command buffer (which is used to set up the TLBs) has a 32 bit size restriction in hardware. There seems to be no way to specify addresses larger than 32 bit. Keep it simple and restict the addresses to the lower 4 GiB range for all coherent DMA memory allocations. Please no
