Add a new drm_crtc_init_with_planes() to allow drivers to provide
specific primary and cursor planes at CRTC initialization. The existing
drm_crtc_init() interface remains to avoid driver churn in existing
drivers; it will initialize the CRTC with a plane helper-created primary
plane and no cursor plane.
v2:
- Move drm_crtc_init() to plane helper file so that nothing in the DRM
core depends on helpers. [suggested by Daniel Vetter]
- Keep cursor parameter to drm_crtc_init_with_planes() a void* until
we actually add cursor support. [suggested by Daniel Vetter]
