board_eth_init() is dead code since commit e524f3a449f5 ("net: Remove
eth_legacy.c"). Remove it.

I'm not sure, all the shenanigans are covered by the new DM-version. The
MDIO mux and iomux controls probably are. The fman configuration
probably isn't. OTOH, nobody cared for years and the called
fm_info_set_phy_address() was also removed years ago.

This also removes fdt_fixup_board_enet() for the ls1043a and ls1046a
because it relies on the local variable "mdio_mux" being initialized by
the board_eth_init().

This patch renames the board directory from board/freescale to
board/nxp because NXP now provides Board Support Packages (BSPs) and
tools for the former Freescale i.MX and other i.MX products.

All relevant references have been updated accordingly. This change does
not affect functionality.
