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.

b/w that the group may be able to use and the system admin can configure
the b/w accordingly.
If the MBA is specified in MB(megabytes) then user can enter the max b/w in MB
rather than the percentage values.
If resctrl is using the software controller (mba_sc) then user can enter the
max b/w in MB rather than the percentage values.
