Snippets: Change Related Portfolio Columns for Mobile

/**
 * Add responsive grid classes to related portfolio entries
 * Note: Only add the classes you need. For example if the default columns
 * are set to 3 no need to define 3 columns again for tablet devices.
 *
 * All responsive column classes use the format span_1_of_{columns}_{device}
 * Devices: tl => tablet landscape
 *			tp => tablet portrait
 *			pl => phone landscape
 *			pp => phone portrait
 *
