Downstream packages like Debian flash-kernel rely on
/proc/device-tree/model
to determine how to install an updated kernel image.
Most dts files provide this property.
This patch adds a model attribute Octeon CPUs.
v2:
Use vendor prefix defined in vendor-prefixes.txt.
Separate model from vendor by comma.
Avoid wildcards.

NAK.
These device tree templates are only used on systems with archaic
versions of u-boot. For all modern OCTEON systems, the device tree is
provided by the firmware and is not under the control of the authors of
the Linux kernel.
Whatever problem you are attempting to solve, almost by definition,
cannot be solved by modifying these files.
We are worse off changing these, and giving people false hope that you
are fixing something, than doing nothing.
