The register and irq definitions in mach/*.h for spear3xx and
spear6xx are now mostly obsolete, after the platforms have been
converted to device tree based probing and the data is now
part of the device tree files.
The misc_regs.h contents are moved into clock.c because that is
the only user, aside from the DMA_CHN_CFG that should eventually
get handled differently. Some of the contents of mach/spear.h
still remain, because they are used to set up the static map table,
timer, uart and auxdata tables, but almost everything got removed.
We might remove everything but the map table as the DT conversion
completes, but that is not a priority. I've also made sure to
make both copies of spear.h more or less identical so we can
eventually combine them.
The spear3?0.h files were only used by the spear3?0.c files, so I
merged the contents in there and removed the bits that were unused.
This is something that should still be looked at.

Add a reg-names property to allow for reg regions to be reference by name
instead of by index. Some devices have multiple register regions which
are more naturally referenced by name.
If the name is available, use it to name the resource when creating a devices.
Otherwise keep the device name.

of_find_matching_node_by_address() can be used to find a device tree
node for a device at a specific address.

This patch changes u32 to __be32 for all "ranges", "prop" and "addr" and
such. Those variables are pointing to the device tree which contains
integers in big endian format.
Most functions are doing it right because of_read_number() is doing the
right thing for them. of_bus_isa_get_flags(), of_bus_pci_get_flags() and
of_bus_isa_map() were accessing the data directly and were doing it wrong.

Resource names appear in human readable output, so when extracting IRQ
and address resources from a device tree node, use the full node name
to give proper context in places like /proc/iomem.

Certain Apple machines don't use the ranges property correctly, but the
workaround should not be applied on other architectures. This patch
disables the workaround for non-powerpc architectures.

Microblaze and PowerPC share a large chunk of code for translating
OF device tree data into usable addresses. Differences between the two
consist of cosmetic differences, and the addition of dma-ranges support
code to powerpc but not microblaze. This patch moves the powerpc
version into common code and applies many of the cosmetic (non-functional)
changes from the microblaze version.

Merge common code between PowerPC and Microblaze. This patch also
moves the prototype of pci_address_to_pio() out of pci-bridge.h and
into prom.h because the only user of pci_address_to_pio() is
of_address_to_resource().
