ipa: Sort algorithm operations based on calling order
Reorder functions in the base ipa::Algorithm and its derived classes to match the calling order: queueRequest(), prepare() and process(). This makes the code flow easier to read. No functional change intended. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Paul Elder <paul.elder@ideasonboard.com> Reviewed-by: Jacopo Mondi <jacopo@jmondi.org>
