In CameraSensor, the mbusCodes() and sizes() accessor functions retrieves all the supported media bus codes and the supported sizes respectively. However, this is quite limiting since the caller probably isn't in a position to match which range of sizes are supported for a particular mbusCode. Hence, the caller is most likely interested to know about the sizes supported for a particular media bus code. This patch transforms the existing CameraSensor::sizes() to CameraSensor::sizes(mbuscode) to achieve that goal. The patch also transforms existing CIO2Device::sizes() in IPU3 pipeline handler to CIO2Device::sizes(PixelFormat) on a similar principle. The function is then plumbed to CameraSensor::sizes(mbusCode) to enumerate the per-format sizes as required in PipelineHandlerIPU3::generateConfiguration().
