karo: tx48: explicitly call tx48_phy_init()

The .phy_init callback in the cpsw_platform_data which hooks the
tx48_phy_init() function is not being used by the cpsw driver.
Call the function explicitly to make sure the ethernet phy is properly
initialized.
Also make sure the RESET_OUT pin of the TX48 module is activated
as early as possible.
