Subject: [PATCH] sculpt: move nitpicker to leitzentrale affinity

During audio and video playback at a high rate by a VMM, nitpicker on the
boot CPU may interfere with the mixer clients, letting them not finish the
schedule RPC at the mixer in time. Moving nitpicker to the same CPU as
leitzentral mitigates the effect at moment.
