ci: add basic etnaviv support
Here is it.. finally.. some CI love for etnaviv.
I have rebased this thing too many times and would like to get it out of my feet.
For the start this is manually trigger-able so that I can get a feeling what will explode on my side. I will start with on GPU model and deqp2. I have devices with GC3000 and GC7000l GPUs that will be added later on.
Btw - the run takes about 7 minutes.
