[PATCH v4 05/11] net: stmmac: dwmac-stm32: Clean up the debug prints

[Christophe Roullier]

From: Marek Vasut <marex at denx.de>

Use dev_err()/dev_dbg() and phy_modes() to print PHY mode instead of
pr_debug() and hand-written PHY mode decoding. This way, each debug
print has associated device with it and duplicated mode decoding is
removed.
