aspeed: Change the "scu" property definition
The Aspeed Watchdog and Timer models have a link pointing to the SCU
controller model of the machine.
Change the "scu" property definition so that it explicitly sets the
pointer. The property isn't optional : not being able to set the link
is a bug and QEMU should rather abort than exit in this case.
