Subject: [PATCH v1 net 2/2] net: lan743x: Fix PHY reset handling during initialization and WOL

Remove lan743x_phy_init from lan743x_hardware_init as it resets the PHY
registers, causing WOL to fail on subsequent attempts. Add a call to
lan743x_hw_reset_phy in the probe function to ensure the PHY is reset
during device initialization.

Fixes: 23f0703c125be ("lan743x: Add main source files for new lan743x driver")
