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

v3:
- Update error handling for new drm_fb_helper funcs. Check using IS_ERR()
  instead of checking for NULL.

Reported-by: Dan Carpenter <dan.carpenter@oracle.com>

v2:
- No changes
