[edk2] [RFC v4 03/13] OvmfPkg: Update dsc to use IoLib from BaseIoLibIntrinsicSev.inf
When SEV is enabled then we must unroll the rep String I/O instructions. The patch updates dsc file to use SEV version of IoLib inf. The main difference between BaseIoLibIntrinsic.inf and BaseIoLibIntrinsicSev.inf is, SEV version checks if its running under SEV enabled guest, If so then it unroll the String I/O (REP INS/OUTS) otherwise fallbacks to rep ins/outs.
