msi-laptop: Support standard ec 66/62 command on MSI notebook and nebook 

Suppport standard ec 66/62 command on MSI notebook and nebook. MSI
netbook and notebook already support 66/62 command, so, add new
get_state function, and put the old model to non-standard model, but
driver still support those old model.
