On a cpu reset normal, we need to clear local cpus. Unfortunately we
need a new API for that, since KVM only exposes one of the three
resets.

Also we need to clear the riccb and the PSW ri mask on a normal reset.
And we need to set the short psw bit indication in the bios when doing
a reset.

Patches are also in my cleanup branch.
v2 of the KVM patch for the resets will be posted soon.
