ARM: davinci: da830-evm: use cell nvmem lookup for mac address
We now support nvmem lookups and cell definitions for machine code. Add relevant data structures for the mac-address stored in at24 EEPROM. Signed-off-by: Bartosz Golaszewski <bgolaszewski@baylibre.com> Signed-off-by: Sekhar Nori <nsekhar@ti.com>
