Say that drm_flip_work_commit() is safe to call in atomic context. Turn
the name into a hyperlink.

Contain struct drm_flip_task and its helper functions
drm_flip_work_allocate_task() and drm_flip_work_queue_task() within
drm_flip_work.c There are no callers outside of the flip-work code.

I just learned that &struct_name.member_name works and looks pretty
even. It doesn't (yet) link to the member directly though, which would
be really good for big structures or vfunc tables (where the
per-member kerneldoc tends to be long).
Also some minor drive-by polish where it makes sense, I read a lot
of docs ...
v2: Comments from Gustavo.

Now that we're using lists instead of kfifo to store drm flip-work tasks
we do not need the size parameter passed to drm_flip_work_init function
anymore.
Moreover this function cannot fail anymore, we can thus remove the return
code.
Modify drm_flip_work_init users to take account of these changes.

Make use of lists instead of kfifo in order to dynamically allocate
task entry when someone require some delayed work, and thus preventing
drm_flip_work_queue from directly calling func instead of queuing this
call.
This allow drm_flip_work_queue to be safely called even within irq
handlers.
Add new helper functions to allocate a flip work task and queue it when
needed. This prevents allocating data within irq context (which might
impact the time spent in the irq handler).

Describe the fifo parameter. It seems like kerneldoc doesn't properly
handle fields defined using a macro, so it will end up complaining about
this anyway and not generate the documentation for it either. At least
the kerneldoc is now complete.

A small helper to queue up work to do, from workqueue context, after a
flip. Typically useful to defer unreffing buffers that may be read by
the display controller until vblank.
