While the i.MX95 MDIO MDC clock is improved by the commit 587acb86d646 ("enetc: Increase eMDIO MDC rate to 2.5 MHz"), other SoCs use different base clock for their MDIO and the MDC clock on those SoCs is set out of specification by the aforementioned commit. The fix for the i.MX95 MDIO MDC has to be done differently, and will be done so in a follow up change. Until that is done, revert the commit to fix the other SoCs.
