There are a few discussions left with regards to this ioctl:
1) the name of the new structs will contain _v2_ on it?
2) what's the best alternative to avoid compat32 issues?
Due to that, let's postpone the addition of this new ioctl to
the next Kernel version, to give people more time to discuss it.

Sometimes, it is desired to create 1:n and n:1 or even
n:n links between different entities with the same
function.
This is actually needed to support DVB devices that
have multiple frontends. While we could do a function
like that internally at the DVB core, such function is
generic enough to be at media-entity, and it could be
useful on some other places.
So, add such function.

Currently, v4l2_device_register() doesn't use the media_device
struct. So, calling media_device_init() could be called either
before or after v4l2_device_register().
Yet, it is a good practice to initialize everything before calling
the register functions. Also, the other drivers call
media_device_init() before registering the V4L2 device.
So, move the call for media_device_init() to happen earlier on
exynos4-is and s3c-camif.
This is just a cleanup patch.

While we need to keep a u64 alignment to avoid compat32 issues,
having the number of entities/pads/links/interfaces represented
by an u64 is incoherent with the ID number, with is an u32.

The struct media_entity_graph was allocated in the stack, limiting the
number of entities that could be reasonably allocated. Instead, move the
struct to struct media_pipeline which is typically allocated using
kmalloc() instead.
The intent is to keep the enumeration around for later use for the
duration of the streaming. As streaming is eventually stopped, an
unfortunate memory allocation failure would prevent stopping the
streaming. As no memory will need to be allocated, the problem is avoided
altogether.
