iwlwifi: rename iwl-4695-rs to iwl-agn-rs
This patch renames iwl-4965-rs to iwl-agn-rs as it provides rate scale capability for all AGN capable iwlwifi drivers. Signed-off-by: Tomas Winkler <tomas.winkler@intel.com> Signed-off-by: Zhu Yi <yi.zhu@intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
