layerscape: Adapt patch to changes in upstream kernel

In kernel v4.4.179 the structure of the scripts/mod/file2alias.c file
changed, this adapts the patch to the changes done in the stable
kernel.

This fixes the following compile problem:
  HOSTCC  scripts/mod/file2alias.o

 ADD_TO_DEVTABLE("fslmc", fsl_mc_device_id, do_fsl_mc_entry);
