arm: mvebu: Espressobin: move FDT fixup into a separate function

Currently, Esspresobin FDT is being fixed up directly in ft_board_setup()
which makes it hard to add support for any other board to be fixed up.

So, lets just move the FDT fixup code to a separate function and call it
if compatible matches, there should be no functional change.
