media: ipu-bridge: Change ov2740 link-frequency to 180 MHz
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.
