Subject: android: camera_device: Break out size calculation
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

As the RAW stream sizes needs to be calculated differently from the
processed one, break out the procedure to calculate the processed
(RGB/YUV) resolutions from initializeStreamConfigurations() in order to
prepare for RAW sizes calculation.
