(This is a repeat of the discussion we had surrounding the ABMC feature.)
By adding "sdciae_capable" to struct rdt_resource the "sdciae" feature
becomes a resctrl fs feature. Any other architecture that has a "similar
but perhaps not identical feature to AMD's SDCIAE" will be forced to also
call it "sdciae" ... sdciae seems like a marketing name to me and resctrl
needs something generic that could later be built on (if needed) by other
architectures.
