etnaviv: check for softpin availability on Halti5 devices
Halti5 uses texture descriptors to control the samplers, and thus needs to know the GPU virtual address for the texture buffers to fill into the descriptor buffer. Without softpin userspace has no control over the GPU VM and also no way to fix up the texture descriptor buffer, so there is no point in creating a screen on a Halti5 device without softpin being available.
