Fixup the FEC driver files 

Some register bits are not defined in the IMX CPUs using this FEC (at least
I did not find anything about them in the related datasheets) and they will
get (partially) a new meaning in the i.MX28 CPU. So, removing them from the
source seems the best way to avoid any accidental usage on i.MX28.
