fs-enet: remove code associated with !CONFIG_PPC_MERGE

Now that arch/ppc is gone we don't need CONFIG_PPC_MERGE anymore remove the dead code associated with !CONFIG_PPC_MERGE. With this change the pre_request_irq() and post_free_irq() calls became nops so they have been removed. Also removed fs_request_irq() and fs_free_irq() and just called request_irq() and free_irq().
