soc/intel/apollolake: add option for SLP_S3_L assertion width
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.
