wifi: iwlwifi: mld: support iwl_mac_power_cmd version 2

Browse Source 
This version fixes the issue that was worked around by
iwl_mld_smps_wa. So for FWs with the new version don't do the
workaround, and set new bit added in this version when appropriate.
While at it, rename iwl_mld_smps_wa to iwl_mld_smps_workaround.
