Jonas Ådahl 227eea1e31 kms-impl-simple: Add fake cursor planes if no real ones
Non-atomic drivers may support drmModeSetCursor() even if no cursor
plane is advertised. To deal with this, add a fake cursor plane for
every CRTC when using MetaKmsImplSimple. This will eventually be
translated to drmModeSetCursor() calls without any explicit cursor plane
usage.
