When initializing a context, the core wants to reset both src and dst
formats. Right now the order doesn't matter, but if we want to have a
valid default width/height on the non-coded/raw format side (src in
case of encoders, dst in case of decoders), we need to reset those
formats in the right order: first the coded-format side, then the other,
such that width and height on the raw format side can be taken from
the coded format.
Let's provide a helper that will reset both formats and make sure this
is done in the right order.

The allegro hardware encoder does not write SPS/PPS nal units into the
encoded video stream. Therefore, we need to write the units in software.
The implementation follows Rec. ITU-T H.264 (04/2017) to allow to
convert between a C struct and the RBSP representation of the SPS and
PPS nal units.
The allegro driver writes the nal units into the v4l2 capture buffer in
front of the actual video data which is written at an offset by the IP
core. The remaining gap is filled with a filler nal unit.

since only the imx5/6 CSI makes use of the frame interval monitor.

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.
Since the VDIC and IC task drivers are no longer platform drivers,
they are now statically linked to imx-media module.
