x86/intel_rdt: Trim whitespace while parsing schemata input
Schemata is displayed in tabular format which introduces some whitespace
to show data in a tabular format.
Writing back the same data fails as the parser does not handle the
whitespace.
Trim the leading and trailing whitespace before parsing.
