platform/x86/intel/pmt: decouple sysfs and namespace
The PMT namespace includes the crashlog sysfs attribute information. Other crashlog version/types may need different sysfs attributes. Coupling the attributes with the namespace blocks this usage. Decouple sysfs attributes from the name space and add them to the specific entry. Reviewed-by: Ilpo Järvinen <ilpo.jarvinen@linux.intel.com> Signed-off-by: Michael J.
