tg3: Fix ethtool loopback test for 5761 BX devices
A CPMU related loopback test bug existed for AX revisions of the 5761. While that errata has been fixed, the CPMU still slows down the core clock too far to run the loopback test successfully. This patch disables the CPMU LINK_SPEED mode just like we do with the AX revisions of the 5761 and all revisions of the 5784.
