conf: add support for specifying CPU "dies" parameter

Recently CPU hardware vendors have started to support a new structure inside the CPU package topology known as a "die". Thus the hierarchy is now: sockets > dies > cores > threads This adds support for "dies" in the XML parser, with the value defaulting to 1 if not specified for backwards compatibility. For example a system with 64 logical CPUs might report <topology sockets="4" dies="2" cores="4" threads="2"/> Reviewed-by: N Jiri Denemark <jdenemar@redhat.com> Reviewed-by: N Daniel Henrique Barboza <danielhb413@gmail.com> Signed-off-by: N Daniel P.
