net/fman: Support both new and legacy FMan Compatibles

Browse Source 
Recently  the FMan Port and MAC compatibles were changed.
This patch aligns the FMan Port and MAC compatibles
to the new FMan device tree binding document.
The FMan device tree binding document can be found in the Linux kernel:
./Documentation/devicetree/bindings/powerpc/fsl/fman.txt

This patch doesn't affect legacy compatibles support.
