[POWERPC] Adapt ipic driver to new host_ops interface, add set_irq_type to set IRQ sense
This converts ipic code to Benh's IRQ mods. For the IPIC, IRQ sense values in the device tree equal those in include/linux/irq.h; that's 8 for low assertion (most internal IRQs on mpc83xx), and 2 for high-to-low change.
spinlocks added to [un]mask, ack operations; default handler and type now set in host_map; and redundant condition check eliminated.
