Two patches from Heiner for the i801 are targeting muxes

discovered while working on some other features. Essentially,
there is a reordering when adding optional slaves and proper
cleanup upon registering a mux device.

Christophe fixes the exit path in the wmt driver that was leaving
the clocks hanging, and the last fix from Tommy avoids false
error reports in IRQ.
