Please don't hijack an infrastructure change that changes nothing for the
GENERIC kernel.

Please start a separate thread about changing how HW random sources are
handled in random(4) if you like.  But that is outside the scope of
this change.

[Adding flexibility to how the HW sources are used will be in one of our
next proposed changes.]
