commit 8f269102baf788aecfcbbc6313b6bceb54c9b990 upstream.
Platform drivers may call stmmac_probe_config_dt() to parse dt, could call stmmac_remove_config_dt() in error handing after dt parsed, so need disable clocks in stmmac_remove_config_dt().
Go through all platforms drivers which use stmmac_probe_config_dt(), none of them disable clocks manually, so it's safe to disable them in stmmac_remove_config_dt().
