x86/intel_rdt: Update schemata read to show data in tabular format

Browse Source 
The schemata file displays data from different resources on all
domains. Its cumbersome to read since they are not tabular and data/names
could be of different widths.  Make the schemata file to display data in a
tabular format thereby making it nice and simple to read.
