In order to provide time for the S0 rails to discharge one needs to be able to set the SLP_S3_L assertion width. The hardware default is 60 microcseconds which is not slow enough on most boards. Therefore provide a devicetree option for the mainboard to set accordingly for its needs. An unset value in devicetree results in a conservative 2 second SLP_S3_L duration.
