Subject[PATCH v2 17/29] net: davinci_emac: use eth_platform_get_mac_address()
Date
From: Bartosz Golaszewski <bgolaszewski@baylibre.com>

We now support nvmem in eth_platform_get_mac_address() and all boards
have the mac-address cells defined. Stop getting the MAC from pdata
and use the dedicated helper.
