Merge common code between Sparc, PowerPC and Microblaze.
Sparc differs in the implementation at this point, so this patch uses
a #ifdef to handle sparc differently for now. The merging of
implementations will occur in a later patch

In preparation to prune things out of the Sparc, PowerPC and Microblaze
asm/prom.h files, change the #include statements to ensure that
even if asm/prom.h is included first, linux/of.h gets to determine the
order in which files are processed.
This patch adds a #include <linux/of.h> to each of the prom.h files
*above* the multi-include protection macros to ensure that linux/of.h
can define things before prom.h gets processed.
At the end of the merge the cross dependencies between the files should
be gone and a sane #include scheme can be restored.

Add sparc_leon enum, M_LEON|M_LEON3_SOC machine. Add compilation of
leon.c in mm and kernel
if CONFIG_SPARC_LEON is defined. Add sparc_leon dependent
initialization to switch statements + head.S.

We need to split up the cpu present mask setup from the cpu_data
initialization, and this is a first step towards that.

Stephen Rothwell noticed that I committed an earlier version
of the patch that didn't have two things fixed:
1) irq_of_parse_and_map() should return "unsigned int" not "int"
and it should return zero for "no irq"
2) irq_dispose_mapping() should be an inline function, not a macro,
for type checking
With feedback and suggestions from Anton Vorontsov.

This allows more OF layer code to be shared between powerpc and
sparc.

On some platforms, the I2C controller is shared between the OS and
OBP. OBP uses this I2C controller to access the EEPROM, and thus is
programmed when the kernel calls prom_setprop().
Wrap such calls with the new of_set_property_mutex.
Relevant I2C bus drivers can grab this mutex around top-level I2C
operations to provide the proper protection.

The majority of this patch was created by the following script:
***
ASM=arch/sparc/include/asm
mkdir -p $ASM
git mv include/asm-sparc64/ftrace.h $ASM
git rm include/asm-sparc64/*
git mv include/asm-sparc/* $ASM
sed -ie 's/asm-sparc64/asm/g' $ASM/*
sed -ie 's/asm-sparc/asm/g' $ASM/*
***
The rest was an update of the top-level Makefile to use sparc
for header files when sparc64 is being build.
And a small fixlet to pick up the correct unistd.h from
sparc64 code.
