powerpc/mpic: Fix mapping of "DCR" based MPIC variants
Commit 31207dab7d2e63795eb15823947bd2f7025b08e2 "Fix incorrect allocation of interrupt rev-map" introduced a regression crashing on boot on machines using a "DCR" based MPIC, such as the Cell blades. The reason is that the irq host data structure is initialized much later as a result of that patch, causing our calls to mpic_map() do be done before we have a host setup. Unfortunately, this breaks _mpic_map_dcr() which uses the mpic->irqhost to get to the device node. This fixes it by, instead, passing the device node explicitely to mpic_map().
