drm: use noop_llseek
The drm device drivers currently allow seeking on the
character device but never care about the actual
file position.
When we change the default llseek operation to be
no_llseek, calling llseek on a drm device would
return an error condition, which is an API change.
Explicitly setting noop_llseek lets us keep the
current API.
