When vkms calls drm_universal_plane_init(), it sets 0 for the possible_crtcs parameter which works well for a single encoder and connector; however, this approach is not flexible and does not fit well for vkms. This commit adds an index parameter for vkms_plane_init() which makes code flexible and enables vkms to support other DRM features.
