Subject: [RFC PATCH 12/17] tc35815: Use standard phy_init_hw() instead of BMCR_RESET bit

The PHY should not be manually reset with the BMCR, as that will undo
board-specific PHY fixups and driver-specific phy->drv->config_init().

Instead, the PHY should be reset using phy_init_hw().

NOTE: Depends on earlier phy_init_hw() patch.
