etnaviv: implement buffer compression
Vivante GPUs have lossless buffer compression using the tile-status bits,
which can reduce memory access and thus improve performance.
This patch only enables compression for "V4" compression GPUs, but the
implementation is tested on GC2000(V1) and GC3000(V2). V1/V2 compresssion
looks absolutely useless, so it is not enabled.
I couldn't test if this patch breaks MSAA, because it looks like MSAA is
already broken.
