[PATCH v2 0/2] Update the handling of the primary plane

[Maíra Canal]

This patchset focus on the proper handling of the primary plane after the
modifications introduced in commit bc0d7fdefec6 ("drm: vkms: Supports to the
case where primary plane doesn't match the CRTC"). Before this commit, the
composition was executed on top of the primary plane. Therefore, the primary
plane needed to cover the entire CRTC and it needed to be visible. After commit
bc0d7fdefec6, this is no longer necessary, as the composition is now executed on
top of the CRTC. So, remove those restrictions to the primary plane.

This patchset increased the vkms IGT test coverage. The following tests are now
passing:

- igt at kms_atomic_transition@plane-toggle-modeset-transition
- igt at kms_atomic_transition@modeset-transition
- igt at kms_atomic_transition@modeset-transition-fencing
- igt at kms_atomic_transition@modeset-transition-nonblocking
- igt at kms_atomic_transition@modeset-transition-nonblocking-fencing
- igt at kms_universal_plane@disable-primary-vs-flip-pipe-a
- igt at kms_universal_plane@universal-plane-pageflip-windowed-pipe-a
- igt at kms_universal_plane@universal-plane-pipe-a-functional

Moreover, this patchset was tested with the vkms IGT testlist and all tests
passed successfully.
