For non-x86 arch, Compiler will throw build error for in/out apis. Including
dummy api function so to pass build.
Note that: For virtio to work for non-x86 arch - RTE_EAL_VFIO is the only
supported method. RTE_EAL_IGB_UIO is not supported for non-x86 arch.
So, Virtio support for arch and supported interface by that arch:
ARCH IGB_UIO VFIO
x86 Y Y
ARM64 N/A Y
PPC_64 N/A Y (Not tested but likely should work, as vfio is
arch independent)
Note: Applicable for virtio spec 0.95
