EmbeddedPkg/NonCoherentIoMmuDxe: Make SetAttributes always succeed

Browse Source 
NonCoherentIoMmuSetAttribute() does nothing except return
EFI_UNSUPPORTED. This was fine when it was introduced, but now, the PCI
bus driver will fail a PCI I/O Map() operation if the call to
SetAttributes() fails.

So return EFI_SUCCESS instead.
