etnaviv: Set SE.CLIP registers, add margins for scissor/clip registers
This fixes rendering of full-screen quads (and other screen-filling
geometry, e.g. ioquake3 walls up-close) on gc3000. It should be a no-op
on other hardware.
- It looks like SE_CLIP registers were not set at all.
I'm amazed that rendering worked without them. Emit them to
avoid issues on gc3000.
- Define constants
ETNA_SE_SCISSOR_MARGIN_RIGHT (0x1119)
ETNA_SE_SCISSOR_MARGIN_BOTTOM (0x1111)
ETNA_SE_CLIP_MARGIN_RIGHT (0xffff)
ETNA_SE_CLIP_MARGIN_BOTTOM (0xffff)
These demarcate the margin (fixp16) between the computed sizes and the
value sent to the chip. I have set these to the numbers used by the
Vivante driver for gc2000. I am not sure whether any old hardware was
relying on the old numbers, or whether those were just a guess. But if
so, these need to be moved to the _specs structure.

etnaviv: Generate new sin/cos instructions on GC3000
Shaders using sin/cos instructions were not working on GC3000.
The reason for this turns out to be that these chips implement sin/cos
in a different way (but using the same opcodes):
- Need their input scaled by 1/pi instead of 2/pi.
- Output an x and y component, which need to be multiplied to
get the result.
- tex_amode needs to be set to 1.
Add a new bit to the compiler specs and generate these instructions
as necessary.

etnaviv: gallium driver for Vivante GPUs
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
