Oops... I left out a "Signed-off-by" on each the 4 patches, so I'll send out a v3.

> 
> The UefiCpuPkg/CpuIo2Dxe driver and the QemuCfgLib library have

> The intent of this patch series is twofold:
> 1) Consolidate I/O Fifo routines into a common BaseIofifoLib library.
> 2) Allow override of BaseIofifoLib for specific platform implementations.
