Subject: [PATCH net-next 15/22] net: stmmac: dwmac-starfive: use devm_stmmac_probe_config_dt()

From: Jisheng Zhang <[email-masked]>
Date: Tue, 29 Aug 2023 18:40:26 +0800

Simplify the driver's probe() function by using the devres
variant of stmmac_probe_config_dt().

The remove_new() callback now needs to be switched to
stmmac_pltfr_remove_no_dt().
