x86/resctrl: Create mba_sc configuration in the rdt_domain
To support resctrl's MBA software controller, the architecture must provide
a second configuration array to hold the mbps_val[] from user-space.
This complicates the interface between the architecture specific code and
the filesystem portions of resctrl that will move to /fs/, to allow
multiple architectures to support resctrl.
Make the filesystem parts of resctrl create an array for the mba_sc
values. The software controller can be changed to use this, allowing
the architecture code to only consider the values configured in hardware.
