net: lan743x: Fix PHY reset handling during initialization and WOL

Browse Source 
[ Upstream commit 82d1096ca8b5dbb3158d707e6fb3ad21c3403a49 ]

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.
