====================
stmmac: convert to devm_stmmac_probe_config_dt

Russell pointed out there's a new devm_stmmac_probe_config_dt()
helper now when reviewing my starfive gmac error handling patch[1].
After greping the code, this nice helper was introduced by Bartosz in
[2], I think it's time to convert all dwmac users to this helper and
finally complete the TODO in [2] "but once all users of the old
stmmac_pltfr_remove() are converted to the devres helper, it will be
renamed back to stmmac_pltfr_remove() and the no_dt function removed."

Link: https://lore.kernel.org/netdev/ZOtWmedBsa6wQQ6+@shell.armlinux.org.uk/ [1]
Link: https://lore.kernel.org/all/20230623100417.93592-1-brgl@bgdev.pl/  [2]

Since v1:
 - rebase on new net-next
 - add make stmmac_{probe|remove}_config_dt static as suggested by Russell.
