drm/nouveau: Use new drm_fb_helper functions 

Use the newly created wrapper drm_fb_helper functions instead of calling
core fbdev functions directly. They also simplify the fb_info creation.

v3:
- Don't touch remove_conflicting_framebuffers

v2:
- remove unused variable pdev in nouveau_fbcon_create
