wifi: iwlwifi: Revert "wifi: iwlwifi: remove support of several iwl_ppag_table_cmd versions"

It turns out that version 6 is still needed.
This change will be brought back once the FW that supports version 6 will no
longer be supported.

This reverts commit 24bc49d1 ("wifi: iwlwifi: remove support of several
iwl_ppag_table_cmd versions")
