drm: Pass 'name' to drm_universal_plane_init()
Done with coccinelle for the most part. It choked on
msm/mdp/mdp5/mdp5_plane.c like so:
"BAD:!!!!! enum drm_plane_type type;"
No idea how to deal with that, so I just fixed that up
by hand.
Also 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_plane_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.
