drm: introduce DRM_CAP_ATOMIC_ASYNC_PAGE_FLIP
This new kernel capability indicates whether async page-flips are
supported via the atomic uAPI. DRM clients can use it to check
for support before feeding DRM_MODE_PAGE_FLIP_ASYNC to the kernel.
Make it clear that DRM_CAP_ASYNC_PAGE_FLIP is for legacy uAPI only.
