panfrost: fix hang by using MALI_PIXEL_KILL_WEAK_EARLY in color preload
Setting zs_update_operation = FORCE_EARLY for color preloads triggers
hangs in the dEQP-VK.rasterization.rasterization_order_attachment_access
depth/stencil tests. I didn't determine why this is the case, but the
DDK uses WEAK_EARLY for color preload, and doing the same here fixes the
hang.
WEAK_EARLY requires ATEST, so I removed .is_blit=true from the compiler
inputs.
There aren't any known hangs outside of the one set of vulkan CTS tests,
and in particular no known hangs in the gallium driver. Because the
reason for the hangs is not understood, I also changed the gallium
driver to use WEAK_EARLY, under the assumption that the same conditions
that trigger the hang in vulkan might occur in GL.
