Commit 885872b722b7 ("MIPS: Octeon: Add Octeon III CN7xxx
interface detection") added RGMII interface detection for OCTEON III,
but it results in the following logs:

[    7.165984] ERROR: Unsupported Octeon model in __cvmx_helper_rgmii_probe
[    7.173017] ERROR: Unsupported Octeon model in __cvmx_helper_rgmii_probe

The current RGMII routines are valid only for older OCTEONS that
use GMX/ASX hardware blocks. On later chips AGL should be used,
but support for that is missing in the mainline. Until that is added,
mark the interface as disabled.

Applied to mips-fixes.
