+ * Function: stm32_phy_boardinitialize

+ * Description:
+ *   Some boards require specialized initialization of the PHY before it can be used.
+ *   This may include such things as configuring GPIOs, resetting the PHY, etc.  If
+ *   CONFIG_STM32_PHYINIT is defined in the configuration then the board specific
+ *   logic must provide stm32_phyinitialize();  The STM32 Ethernet driver will call

+ * Parameters:
+ *   intf - Always zero for now.
