fec: Fix the order for enabling/disabling the clocks

Browse Source 
On fec_probe the clocks are enabled in the following order:

clk_ahb -> clk_ipg -> clk_enet_out -> clk_ptp

, so in the error and remove paths we should disabled them in the opposite
order.

Also fix the order in the suspend/resume functions.
