<?php $alias = get_theme_mod('rev_alias'); ?>
<?php if ($alias) : ?>
    <?php putRevSlider($alias) ?>
<?php endif; ?>

Replace it with this and add your aliases:

<?php if ( wp_is_mobile() ) : ?>
    <?php putRevSlider("youraliasformobile") ?>
<?php else : ?>
    <?php putRevSlider("youraliasfordesktop") ?>
<?php endif; ?>
