In order that we can use eth_env_* even when CONFIG_NET isn't set, move
these functions to environment code from net code.
This fixes failures such as:
board/ti/am335x/built-in.o: In function `board_late_init':
board/ti/am335x/board.c:752: undefined reference to `eth_env_set_enetaddr'
u-boot/board/ti/am335x/board.c:766: undefined reference to `eth_env_set_enetaddr'
which caters for use cases such as:
commit f411b5cca4 ("board: am335x: Always set eth/eth1addr environment
variable")
when Ethernet is required in Linux, but not U-Boot.
