MIPS: OCTEON: mark RGMII interface disabled on OCTEON III
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.
