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.
It is suggested by IEEE Std 1275-1994.

This patch adds a model attribute for Octeon CPUs.

The ePAPR 1.1 standard says:

2.3.2 model

Property: model
Value type: <string>
Description:
The model property value is a <string> that specifies the
manufacturer’s model number of the device.

The recommended format is: “manufacturer,model”, where manufacturer
is a string describing the name of the manufacturer (such as a stock
ticker symbol), and model specifies the model number.

Example:
model = “fsl,MPC8349EMITX”;
