REF: https://bugzilla.tianocore.org/show_bug.cgi?id=4496
PI spec defined the `Register` function input argument `Delay` as output.
However, this parameter should be used to define the minmal time delay
the callback should fire. Thus it should be an input parameter.
This change fixed the argument type.
