etnaviv: SINGLE_BUFFER support on GC3000
This patch adds support for the SINGLE_BUFFER feature on GC3000 GPUs, which allows rendering to a single buffer using multiple pixel pipes. This feature is always used when it is available, which means that multi-tiled formats are no longer being used in that case, and all buffers will be normal (super)tiled. This mimics the behavior of the blob on GC3000. - Because the same format can be used to render to and texture from, this avoids an extra resolve pass when rendering to texture. - i.MX6qp includes a PRE which can scan-out directly from tiled formats, avoiding untiling overhead.
