cpu_eth_init is no longer called for dm enabled eth drivers, this was causing the sunxi gmac eth controller to no longer work in u-boot. This commit fixes this by calling the clock, reset and pinmux setup function from s_init() and enabling the phy power pin (if any) from board_init(). The enabling of phy power cannot be done from s_init because it uses dm and dm is not ready yet at this point. Note that the mdelay is dropped as the phy gets enabled much earlier now, so it is no longer needed.
