This patch removes the declaration of the function 'of_get_cpu_node'
which is not defined for openrisc. This is in preparation to move
it's definition from PPC to DT common code.
Again it could be there as it was originally copied from powerpc.

Several architectures define their own empty irq_dispose_mapping(). Since
the irq_domain code is centralized now, there is little need to do so. This
patch removes them and creates a new empty copy when !CONFIG_IRQ_DOMAIN is
selected.
The patch also means that IRQ_DOMAIN becomes selectable on all architectures.

The OpenRISC architecture uses the device tree infrastructure for the
platform description. This is currently limited to having a device tree
built into the kernel, but work is underway within the OpenRISC project
to define how this device tree blob should be passed into the kernel from
an external resource.
Patch contains a single example DTS file to go with the defconfig for
or1ksim.
