panfrost: Enable QUAD_STRIP and POLYGON on v6

I wrote fiction about dreaming that these were supported but after
waking finding that they were not. Somehow I came to consider that
fiction as fact and I never thought to test if they did work.

While reverse engineering the polygon list format, I found that these
were supported after all.
