x86/intel_rdt/mba_sc: Add schemata support
Currently when user updates the "schemata" with new MBA percentage
values, kernel writes the corresponding bandwidth percentage values to
the IA32_MBA_THRTL_MSR.
When MBA is expressed in MBps, the schemata format is changed to have the
per package memory bandwidth in MBps instead of being specified in
percentage. Do not write the IA32_MBA_THRTL_MSRs when the schemata is
updated as that is handled separately.
