net: ftmac100: add an opportunity to get ethaddr from the platform

Browse Source 
This driver always generated a random ethernet address. Leave it as a
fallback solution, but add a call to platform_get_ethdev_address().
Handle EPROBE_DEFER returned from platform_get_ethdev_address() to
retry when EEPROM is ready.
