The Hantro driver uses a hardcoded value for the bus_info field in the
media device and |struct v4l2_capability|. This worked well when there
was just one device. However with the iMX.8 series we are now seeing
two Hantro blocks on the same chip. The static bus_info is no longer
sufficient for differentiating devices.
Since commit f2d8b6917f ("media: v4l: ioctl: Set bus_info in
v4l_querycap()"), the V4L2 core provides a default value for the
bus_info field for platform and PCI devices. This value will match
the default value for media devices added by commit cef699749f
("media: mc: Set bus_info in media_device_init()"). These defaults
are stable and device-specific.
Drop the static bus_info values from the hantro driver and use the
defaults.

Before this change, the driver would return EINVAL, which is also invalid
but worked in GStreamer. The original intent was not to implement it, hence
the -ENOTTY return in this change. While drivers should implement
ENUM_FRMSIZE for all formats and queues, this change is limited in scope to
fix the regression.

The ov5670 driver registers three controls as read-only:
- V4L2_CID_PIXEL_RATE
- V4L2_CID_LINK_FREQ
- V4L2_CID_HBLANK
The driver updates the range of HBLANK with __v4l2_ctrl_modify_range()
and updates the values of PIXEL_RATE and LINK_FREQ with an
explicit call to __v4l2_ctrl_s_ctrl() in ov5670_set_pad_format() time.
This causes the .set_ctrl handler to be called on these controls
causing a non-fatal warning to be emitted:
ov5670_set_ctrl Unhandled id:0x9e0902, val:0x824
This is currently only critical for HBLANK, as LINK_FREQ and PIXEL_RATE
currently only support a single value, and the v4l2-ctrl framework skips
calling .set_ctrl() if the current control value is not changed.
Expand the ov5670_set_ctrl() callback to handle the above controls
to remove the above warning and defend against future expansions
of the supported pixel rates and link frequencies.
Also be stricter and return an error value if a control is actually not
handled.

Currently all driver's modes use an analog crop rectangle of size

implementation, ad an .analog_crop field to the sensor's modes
definitions, to make sure that if any mode gets added, its crop
rectangle will be defined as well.
While at it re-sort the modes' field definition order to match the
declaration order and initialize the crop rectangle in init_cfg().
