Alyssa Rosenzweig 4c7a44413a mesa,gallium: Revert "Make point coord origin a CAP"
This reverts commit e749f67f89, which added a CAP
to support drivers that can only do upside-down point coordinates. That was
added specifically for Asahi, since Metal's point coordinate convention is
opposite Mesa's. Since then, additional reverse-engineering aided by the PowerVR
headers led me to the bit doing the flip in hardware, so Asahi does not use the
CAP since baadc1ec13 ("asahi: Don't use lower_wpos_pntc"). Garbage collect it.

[If it's needed for future hardware, we can revive it. But the plan is Vulkan
anyway.]
