Documentation: x86: Clarify MBA takes MB as referring to mba_sc
"If the MBA is specified in MB then user can enter the max b/w in MB" is a tautology. How can the user know if the schemata takes a percentage or a MB/s value? This is referring to whether the software controller is interpreting the schemata's value. Make this clear.
