panfrost: Set tiler descriptor sampler pattern

Bifrost requires this to match the framebuffer descriptor's sample
pattern, but we were leaving the default (single-sampled)
unconditionally, leading to undefined behaviour.

It is unknown if this fixes any user-visible bugs, but without the
commit the descriptor is likely out-of-spec.
