ozone: Remove primary plane optimization.

ozone: Remove primary plane optimization.

Chrome browser compositor sends the primary buffer as a
normal overlay, therefore the optimization to replace the
primary plane can be done earlier in the browser compositor (crrev.com/2281033003).

This CL removes the optimization in Ozone.

We moved the primary plane optimization in the chrome browser compositor:
crrev.com/2281033003.

The problem we found is that if there is a crtc that supports only one plane,
ozone would reject the configuration of two fullscreen planes because the
optimization
would happen after checking if there are available planes.


This optimization in ozone is no longer needed. What do you think about getting
rid of it?

If you want to leave it, I'll just send you another CL that cleans up all the
hacks I added.

lgtm ... This is awesome! Thank you for getting rid of the workarounds in Ozone.

we don't use ozone drm platform ... so it's fine for us.
