MLK-16118-6 net: fec_mxc: Add the init_clk_fec function 

When the power domain driver is enabled, we need to enable clocks after power
domain on. So the clock settings can't set in board_init, needs to set them
when the device is probed. Add this weak function in driver, that SoC codes
can implement the clock settings.
