drm: Pass 'name' to drm_crtc_init_with_planes()
Done with coccinelle for the most part. However, it thinks '...' is
part of the semantic patch, so I put an 'int DOTDOTDOT' placeholder
in its place and got rid of it with sed afterwards.
I didn't convert drm_crtc_init() since passing the varargs through
would mean either cpp macros or va_list, and I figured we don't
care about these legacy functions enough to warrant the extra pain.
