soc/intel/common: Implement __weak smihandler_soc_disable_busmaster

Currently all implemented smihandler_soc_disable_busmaster functions
are actually doing exactly same thing to avoid bus master disable on
PMC. To remove duplicated code, this commit changes the default
function to skip pmc device bus master disable.
