What is the difference between stmmac_platform.{c,h} and
stmmac_plat_lib.{c,h} files? It isn't clear really. In perspective it
may cause confusions like mixed definitions in both of these files.

Why not to use the stmmac_platform.{c,h} instead of adding one more
file? Especially seeing it already has some generic
platform/glue-drivers helpers like:
stmmac_get_platform_resources() <- especially this one.
(devm_)stmmac_probe_config_dt()
stmmac_remove_config_dt()
stmmac_pltfr_init()
stmmac_pltfr_exit()
(devm_)stmmac_pltfr_probe()
stmmac_pltfr_remove()
stmmac_pltfr_suspend()
stmmac_pltfr_resume()
stmmac_runtime_suspend()
stmmac_runtime_resume()
stmmac_pltfr_noirq_suspend()
stmmac_pltfr_noirq_resume()
All of them look like being decent to be defined in the generic
platform library methods too.
