This patch drops the powerpc-specific irq_host structures and uses the common irq_domain strucutres defined in linux/irqdomain.h. It also fixes all the users to use the new structure names. Renaming irq_host to irq_domain has been discussed for a long time, and this patch is a step in the process of generalizing the powerpc virq code to be usable by all architecture. An astute reader will notice that this patch actually removes the irq_host structure instead of renaming it. This is because the irq_domain structure already exists in include/linux/irqdomain.h and has the needed data members.
