Because the IPU sub-devices VDIC and IC are not present in the
device-tree, platform devices were created for them instead. This
allowed these sub-devices to be added to the media device's async
notifier and registered asynchronously along with the other
sub-devices that do have a device-tree presence (CSI and devices
external to the IPU and SoC).
But that approach isn't really necessary. The IPU sub-devices don't
actually require a backing device (sd->dev is allowed to be NULL).
And that approach can't get around the fact that the IPU sub-devices
are not part of a device hierarchy, which makes it awkward to retrieve
the parent IPU of these devices.
By registering them synchronously, they can be registered from the CSI
async bound notifier, so the init function for them can be given the CSI
subdev, who's dev->parent is the IPU. That is a somewhat cleaner way
to retrieve the parent IPU.
So convert to synchronous registration for the VDIC and IC task
sub-devices, at the time a CSI sub-device is bound. There is no longer
a backing device for them (sd->dev is NULL), but that's ok. Also
set the VDIC/IC sub-device owner as the IPU, so that a reference can
be taken on the IPU module.

moderated list:ARM/FREESCALE IMX / MXC ARM ARCHITECTURE,
open list
Re-organize modules, and which objects are linked into those modules, so
that:
- imx6-media (renamed from imx-media) is the media driver module for
imx5/6 only, and has no symbol exports. The IPU internal subdevice
objects now link directly with imx6-media.
- imx6-media-csi (renamed from imx-media-csi) is the subdev driver
module for imx5/6 CSI. It is now linked direcly with imx-media-fim,
since only the imx5/6 CSI makes use of the frame interval monitor.
- imx-media-common now only contains common code between imx5/6 and imx7
media drivers. It contains imx-media-utils, imx-media-of,
imx-media-dev-common, and imx-media-capture. In order to acheive that,
some functions common to imx5/6 and imx7 have been moved out of
imx-media-dev.c and into imx-media-dev-common.c.
