ipu3: cio2: Replicate CameraSensor::getFormats() to a member function

This prepares a base to introduce custom selection of sensor format
based on platform(Soraka or Nautilus) constraints. The changes in
selection policy will be introduced in a subsequent patch.

The function is copied from CameraSensor::getFormat() in the IPU3
pipeline handler code to be later changed on top.

The copy is not verbatim and has a minor change as follows:
CameraSensor::getFormats() has access to a V4L2Subdevice::Formats
internally and use it directly to iterate over supported camera sensor
frame sizes. The copy is adapted to use the CameraSensor::sizes(mbusCode)
instead, to enumerate over the supported frame sizes as per
mbusCodesToPixelFormat map.

No functional changes in this patch.
