net: fec: optimize the clock management to save power
Add below clock management to save fec power: - After probe, disable all clocks incluing ipg, ahb, enet_out, ptp clock. - Open ethx interface enable necessary clocks. Close ethx interface disable all clocks. The patch also encapsulates the all enet clocks enable/disable to .fec_enet_clk_enable(), which can reduce the repetitional code in driver.
