media: add helpers for memory-to-memory media controller
A memory-to-memory pipeline device consists in three
entities: two DMA engine and one video processing entities.
The DMA engine entities are linked to a V4L interface.
This commit add a new v4l2_m2m_{un}register_media_controller
API to register this topology.
For instance, a typical mem2mem device topology would
look like this:
Device topology
- entity 1: source (1 pad, 1 link)
type Node subtype V4L flags 0
pad0: Source
-> "proc":1 [ENABLED,IMMUTABLE]
- entity 3: proc (2 pads, 2 links)
type Node subtype Unknown flags 0
pad0: Source
-> "sink":0 [ENABLED,IMMUTABLE]
pad1: Sink
<- "source":0 [ENABLED,IMMUTABLE]
- entity 6: sink (1 pad, 1 link)
type Node subtype V4L flags 0
pad0: Sink
<- "proc":0 [ENABLED,IMMUTABLE]

media: mark entity-intf links as IMMUTABLE
Currently links between entities and an interface are just marked as
ENABLED. But (at least today) these links cannot be disabled by userspace
or the driver, so they should also be marked as IMMUTABLE.
It might become possible that drivers can disable such links (if for some
reason the device node cannot be used), so we might need to add a new link
flag at some point to mark interface links that can be changed by the driver
but not by userspace.
