Subject[PATCH 1/2] drm/vkms: Use index instead of 0 in possible crtc
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.
