* 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_SAMV7_PHYINIT is defined in the configuration
* then the board specific logic must provide sam_phyinitialize();
* the PHY, etc. If CONFIG_SAMV7_EMAC0_PHYINIT or
* CONFIG_SAMV7_EMAC1_PHYINIT is defined in the configuration then the
* board specific logic must provide sam_phyinitialize();
* The SAMV7 Ethernet driver will call this function one time before it
* first uses the PHY.
*
* Input Parameters:
* intf - Always zero for now.
* intf - 0 for EMAC0 and 1 for EMAC1.
*
* Returned Value:
* OK on success; Negated errno on failure.
