wifi: iwlwifi: make ppag versioning clear
We used to have in iwl_ppag_table_cmd v2, that covered multiple FW
versions of the command (2-6), so we just called it v2, and v3 for FW
version 7. This is a bit confusing, and now v2 actually covers only FW
version 5. Rename v2 to v5 and v3 to v7 so we don't have a different
versioning than the FW has.
