I think this patch is fixing a bug, right? We weren't
previously clearing CR for the hardware reset. If so,
that's worth noting in the commit message.

Generally we prefer not to do this for the hardware reset
function, as it makes it harder to see what the reset
is doing (eg to confirm that it isn't changing qemu IRQ
state). You can have a common helper function to do the
work of the reset though if that helps.
