 stmmac_pltfr_remove

Now, all users of the old stmmac_pltfr_remove() are converted to the
devres helper, it's time to rename stmmac_pltfr_remove_no_dt() back to
stmmac_pltfr_remove() and remove the old stmmac_pltfr_remove().

From: Jisheng Zhang <jszhang@kernel.org>
Date: Sat, 16 Sep 2023 15:58:29 +0800
Subject: [PATCH 23/23] net: stmmac: make stmmac_{probe|remove}_config_dt
 static

Now there's no external users of these two functions, make them static
so that there aren't any new usages of stmmac_probe_config_dt().

To avoid forward declaration, move stmmac_remove_config_dt() location.
