ath79: utilize nvmem on Netgear EX7300 v2

Browse Source 
mtd-mac-address should no longer be used after commit 5ae2e786395c
("kernel: drop support for mtd-mac-address"). Convert it to nvmem-cells.

While at it, also convert OpenWrt's custom mtd-cal-data property and
userspace pre-calibration data extraction to the nvmem implementation.

Note: nvmem-cells in QCN5502 wmac has not been tested.

Fixes: c32008a37b81 ("ath79: add partial support for Netgear EX7300v2")
