The most common match semantic is an exact match based on the device node.
So provide a default implementation that does this, and hook it up if no
match routine is specified.

The majority of irq_host implementations (3 out of 4) are associated
with a device_node, and need to stash it somewhere. Rather than having
it somewhere different for each host, add an optional device_node pointer
to the irq_host structure.

Adds utility routines used by 52xx device drivers and board support
code.  Main functionality is to add device nodes to the of_platform_bus,
retrieve the IPB bus frequency, and find+ioremap device registers.

There is no need to expose these settings outside the scope
of the interrupt controller code itself.

This adds support for the MPC52xx Interrupt controller for
ARCH=powerpc.

It includes the main code in arch/powerpc/sysdev/ as well as a header
file in include/asm-powerpc.
