This consolidates the routines of_find_node_by_path, of_find_node_by_name,
of_find_node_by_type and of_find_compatible_device. Again, the comparison
of strings are done differently by Sparc and PowerPC and also these add
read_locks around the iterations.

This requires creating dummy of_node_{get,put} routines for sparc and
sparc64. It also adds a read_lock around the parent accesses.

The only change here is that a readlock is taken while the property list
is being traversed on Sparc where it was not taken previously.
Also, Sparc uses strcasecmp to compare property names while PowerPC
uses strcmp.

The only difference here is that Sparc uses strncmp to match compatibility
names while PowerPC uses strncasecmp.

This creates drivers/of/base.c (depending on CONFIG_OF) and puts
the first trivially common bits from the prom.c files into it.

This creates linux/of.h and includes asm/prom.h from it.
We also include linux/of.h from asm/prom.h while we transition.

This starts bringing the PowerPC and Sparc implemetations back closer
together.

Finally, we actually change the functions themselves.

Another powerpc compatibility item, this will allow us to share
more code with them.

The idea is to fully construct the device register and
interrupt values into these of_device objects, and convert
all of SBUS, EBUS, ISA drivers to use this new stuff.
Much ideas and code taken from Ben H.'s powerpc work.
