Fix checkpatch.pl warnings of required spaces around '+' sign in
multiple lines in octeon-stubs.h by adding spaces. Also add space before
parentheses in the same file to fix checkpatch.pl warning.

This driver has been in the tree since 2009 with no real movement to get
it out. Now it is starting to cause build issues and other problems for
people who want to fix coding style problems, but can not actually build
it.
As nothing is happening here, just delete the module entirely.

Remove a coding style error from the Octeon driver's tree and keep
checkpatch.pl a little quieter.
Being a white-spaces patch the chances of breakage are minimal; we don't
have the hardware to run this driver so we built it with COMPILE_TEST
enabled on an x86 machine.

When building for a non-Cavium MIPS system with COMPILE_TEST=y, the
Octeon ethernet driver hits a number of issues due to use of macros
provided only for CONFIG_CAVIUM_OCTEON_SOC=y configurations. For
example:
drivers/staging/octeon/ethernet-rx.c:190:6: error:
'CONFIG_CAVIUM_OCTEON_CVMSEG_SIZE' undeclared (first use in this function)
drivers/staging/octeon/ethernet-rx.c:472:25: error:
'OCTEON_IRQ_WORKQ0' undeclared (first use in this function)
These come from various asm/ headers that a non-Octeon build will be
using a non-Octeon version of.
Fix this by using the octeon-stubs.h header for non-Cavium MIPS builds,
and only using the real asm/octeon/ headers when building a Cavium
Octeon kernel configuration.
This requires that octeon-stubs.h doesn't redefine XKPHYS_TO_PHYS, which
is defined for MIPS by asm/addrspace.h which is pulled in by many other
common asm/ headers.

Fix this by replacing casts to "u64" by casts to "uintptr_t", which is
either 32-bit or 64-bit, and adding an intermediate cast to "uintptr_t"
where needed.
