imx8mn-var-som: Simplify FEC initialization
With DM enabled, there is no need for board code to initialize
the FEC interface.
The ethernet PHYs on the symphony carrier board have a dedicated
crystal/oscillator. If the SOM has the EC configuration option
(onboard ethernet PHY), it also has a dedicated crystal/oscillator.
So in all cases, there is no need to enable the RGMII TX clk output.
This follows a similar change introduced by Fabio Estevam:
