When removing prom.h include by of.h, several OF headers will no longer
be implicitly included. Add explicit includes of of_*.h as needed.

The commit bae1d8f199 (linux-next)
"irq_domain/powerpc: Use common irq_domain structure instead of irq_host"
made this change:
-static struct irq_host *flipper_irq_host;
+static struct irq_domain *flipper_irq_host;
and this change:
-static struct irq_host *hlwd_irq_host;
+static struct irq_domain *hlwd_irq_host;
The intent was to change the type, and not the name, but then in a
couple of instances, it looks like the sed to change the irq_domain_ops
name inadvertently also changed the irq_host name where it was not
supposed to, causing build failures.

Each revmap type has different arguments for setting up the revmap.
This patch splits up the generator functions so that each revmap type
can do its own setup and the user doesn't need to keep track of how
each revmap type handles the arguments.
This patch also adds a host_data argument to the generators. There are
cases where the host_data pointer will be needed before the function returns.
ie. the legacy map calls the .map callback for each irq before returning.
v2: - Add void *host_data argument to irq_domain_add_*() functions
- fixed failure to compile
- Moved IRQ_DOMAIN_MAP_* defines into irqdomain.c

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.

Add support for the dual interrupt controller included in the "Hollywood"

This interrupt controller serves both the Broadway processor (as a cascade)
and the Starlet processor, and is used to manage interrupts for the
