[PATCH v2] mx6sabresd: Convert ethernet to driver model

[Alifer Moraes]

Convert imx6sabresd ethernet to driver model to fix the following warning:

===================== WARNING ======================
This board does not use CONFIG_DM_ETH (Driver Model
for Ethernet drivers). Please update the board to use
CONFIG_DM_ETH before the v2020.07 release. Failure to
update by the deadline may result in board removal.
See doc/driver-model/migration.rst for more info.
====================================================

Changes since v1:

- Also removed unused function board_eth_init() to avoid building warnings (Stefano)
