The only known devices that use an ov2740 sensor in combination with
the ipu-bridge code are various Lenovo ThinkPad models, which all
need the link-frequency to be 180 MHz for things to work properly.
The ov2740 driver used to only support 360 MHz link-frequency,
which is why the ipu-bridge entry used 360 MHz, but now the
ov2740 driver has been extended to also support 180 MHz.
The ov2740 is actually used with 360 MHz link-frequency on Chromebooks.
On Chromebooks the camera/sensor fwnode graph is part of the ACPI tables.
The ipu-bridge code is used to dynamically generate the graph when it is
missing, so it is not used on Chromebooks and the ov2740 will keep using
360 MHz link-frequency there as before.

On various Lenovo Thinkpad models with an ov2740 sensor the 360 MHz
link frequency is not supported.
Add support for 180 MHz link frequency, even though this has half the
pixel clock, this supports the same framerate by using half the VTS value
(significantly reducing the amount of empty lines send during vblank).
Normally if there are multiple link-frequencies then the sensor driver
choses the lowest link-frequency still usable for the chosen resolution.
In this case the board supports only 1 link-frequency. Which frequency
is supported is checked in ov2740_check_hwcfg() and then a different
set of supported_modes (using only the supported link-freq) is selected.
The register settings for this were taken from the ov2740 sensor driver
in the out of tree IPU6 driver:

bc0e8d91fe ("media: v4l: subdev: Switch to stream-aware state

v4l2_subdev_state_get_crop() function to be dereferenced. It however
missed that the atmel-isi driver creates the v4l2_subdev_state instance
on the stack (which it shouldn't do, but that's a separate problem),
without initializing the sd field. This results in a null pointer
dereference.
Fix it by initializing the sd field.
