Remove all kernel-doc notation in arch/mips/cavium-octeon/executive/.
This removes dozens of kernel-doc warnings.
Most of these functions are static and don't need to be documented
with kernel-doc.
The function comments are still present for anyone who wants to read them.
These files are part of the OCTEON SDK so presumably they are documented
there as well.

Historically a lot of these existed because we did not have
a distinction between what was modular code and what was providing
support to modules via EXPORT_SYMBOL and friends. That changed
when we forked out support for the latter into the export.h file.
This means we should be able to reduce the usage of module.h
in code that is obj-y Makefile or bool Kconfig. In the case of
some code where it is modular, we can extend that to also include
files that are building basic support functionality but not related
to loading or registering the final module; such files also have
no need whatsoever for module.h
The advantage in removing such instances is that module.h itself
sources about 15 other headers; adding significantly to what we feed
cpp, and it can obscure what headers we are effectively using.
Since module.h might have been the implicit source for init.h
(for __init) and for export.h (for EXPORT_SYMBOL) we consider each
instance for the presence of either and replace/add as needed.
Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.
Build coverage of all the mips defconfigs revealed the module.h
header was masking a couple of implicit include instances, so
we add the appropriate headers there.

arch/mips/cavium-octeon/executive and asm/octeon.
These files are used to coordinate resource sharing between all of
the programs running on the OCTEON SOC. The OCTEON processor has many
CPU cores (current parts have up to 16, but more are possible). It
also has a variety of on-chip hardware blocks for things like network
acceleration, encryption and RAID.
One typical configuration is to run Linux on several of the CPU cores,
and other dedicated applications on the other cores.
Resource allocation between the various programs running on the system
(Linux kernel and other dedicated applications) needs to be
coordinated. The code we use to do this we call the 'executive'. All
of this resource allocation and sharing code is gathered together in
the executive directory.
Included in the patch set are the following files:
cvmx-bootmem.c and cvmx-sysinfo.c -- Coordinate memory allocation.
All memory used by the Linux kernel is obtained here at boot time.
cvmx-l2c.c -- Coordinates operations on the shared level 2 cache.
octeon-model.c -- Probes chip capabilities and version.
The corresponding headers are in asm/octeon.
