[edk2] [PATCH] UefiCpuPkg: CpuIo2Dxe: optimize FIFO reads and writes of IO ports

* Short description: The CpuIoServiceRead() and CpuIoServiceWrite() functions transfer data between memory and IO ports with individual Io(Read|Write)(8|16|32) function calls, each in an appropriately set up loop. On the Ia32 and X64 platforms however, FIFO reads and writes can be
