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.
