net: ethernet: mtk_eth_soc: handle probe deferral
Move the call to of_get_ethdev_address to mtk_add_mac which is part of
the probe function and can hence itself return -EPROBE_DEFER should
of_get_ethdev_address return -EPROBE_DEFER. This allows us to entirely
get rid of the mtk_init function.
The problem of of_get_ethdev_address returning -EPROBE_DEFER surfaced
in situations in which the NVMEM provider holding the MAC address has
not yet be loaded at the time mtk_eth_soc is initially probed. In this
case probing of mtk_eth_soc should be deferred instead of falling back
to use a random MAC address, so once the NVMEM provider becomes
available probing can be repeated.
