Subject: [net-next][PATCH 2/4] net: cadence: switch to using nvmem_get_mac_address()

From: Bartosz Golaszewski <bgolaszewski@...libre.com>

We now have a generalized helper routine to read the MAC address from
nvmem which takes struct device as argument. The nvmem subsystem will
then try device tree first before all other potential providers.
