sfc: Fix conditions for MDIO self-test
The MDIO self-test should not be run on boards without an MDIO PHY, such as SFN5122F-R3 and later revisions. It should also not try to address a specific MMD in an MDIO clause 22 PHY. Check the mode_support field to decide which mode to use, if any. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>
