Most drivers don't need it and shouldn't need it because it can't be used
in some cases (indirect draws, primitive restart, count from streamout).

This adds native fence fd support to etnaviv, similarly to commit
0b98e84e9b ("freedreno: native fence fd"), enabled for kernel
driver version 1.1 or later.

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.

If we render to rb swapped format we will create a shader variant doing
the involved swizzing in the pixel shader.

In case ctx->stream == NULL the fail label gets executed where
pctx gets dereferenced - too bad pctx is NULL in that case.

Notes:
- make sure the default size is large enough to handle all state trackers
- pipe wrappers don't receive transfer calls from stream_uploader, because
pipe_context::stream_uploader points directly to the underlying driver's
stream_uploader (to keep it simple for now)
v2: add error handling to nv50, nvc0, noop
v3: set const_uploader

This driver supports a wide range of Vivante IP cores like GC880,
GC1000, GC2000 and GC3000.
Changes from V1 -> V2:
- added missing files to actually integrate the driver into build system.
- adapted driver to new renderonly API
