[PATCH 3/3] media: ipu-bridge: Add sensor configuration for OV5675 (OVTI5678)

[Sahan Nissanka]

The front camera of the Dell Latitude 7320 Detachable is an OV5675
described in ACPI as OVTI5678. Without an entry here ipu-bridge creates
no software node for it, so no fwnode endpoint exists and the sensor
cannot be connected to the IPU6 even once a driver binds it:

  intel-ipu6 0000:00:05.0: Found supported sensor OVTI8856:00
  intel-ipu6 0000:00:05.0: Connected 1 cameras

450 MHz is OV5675_LINK_FREQ_450MHZ, the only link frequency ov5675.c
supports, and matches the two data lanes the machine's SSDB reports.

With this entry both cameras are found and the front sensor appears in
the media graph:

  intel-ipu6 0000:00:05.0: Found supported sensor OVTI5678:00
  intel-ipu6 0000:00:05.0: Found supported sensor OVTI8856:00
  intel-ipu6 0000:00:05.0: Connected 2 cameras
