Replace the generic "is this plane primary" for a plane::async_flip
check, so DRM follows the plane restrictions set by the driver.

Allow userspace to use explicit synchronization with atomic async flips.
That means that the flip will wait for some hardware fence, and then
will flip as soon as possible (async) in regard of the vblank.

Given that prop changes may lead to modesetting, which would defeat the
fast path of the async flip, refuse any atomic prop change for async
flips in atomic API. The only exception is the framebuffer ID to flip
to. Currently the only plane type supported is the primary one.

So, I would not recommend to use it in any product, even downstream.
