It is actually really simple. If you downgrade packages in ArchLinux you can use "downgrader" for official repositories, but for AUR packages you need to do it manually. The problem I had is that I need <3.0.0 of php-codesniffer. Since php-codesniffer-drupal has that dependency.

Find the right version from AUR git commits, in my case php-codesniffer package. I downloaded snapshot form "Updated to latest stable v2.8.1" commit.

Just extract the snapshot, cd into it and run "makepkg -i".

To avoid overwriting the package on update we add it to IgnorePkg in "/etc/pacman.conf".
