From: Joakim Zhang <qiangqing.zhang@xxxxxxx>
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().
Fixes: commit d2ed0a7755fe ("net: ethernet: stmmac: fix of-node and fixed-link-phydev leaks")
