Steps for doing this using phpMyAdmin settings without any problem or requirements to change configs in php my.ini or defining .htaccess file:

1. Goto your phpMyAdmin install path (ex. /usr/share/phpMyAdmin/ on my centos7) and find create_tables.sql in one of its subfolders (phpMyAdmin/sql/create_tables.sql in my 4.4.9 version.) and execute whole file contents on your current phpMyAdmin site from your web browser. This will create a database named phpmyadmin which can keep all your phpMyAdmin options saved permanently.
2. In phpMyAdmin's config.inc.php (located on /etc/phpMyAdmin/ in my centos7 server) find the commented line $cfg['Servers'][$i]['pmadb'] = 'phpmyadmin'; and uncomment it (Now phpMyAdmin will use that custom database we generated in previous step).
3. Goto phpMyAdmin from web browser and goto Server >> Settings >> Features >> "Login Cookie Validity" as in picture described by Pavnish and set the desired value. It works now.
