This patch converts legacy Ralink SoCs and MT7620 WiFi calibration
data to NVMEM format. The EEPROM size is 0x200.

Define nvmem-cells and convert mtd-mac-address to nvmem implementation.
The conversion is done with an automated script.

Rework patch 681-NET-add-mtd-mac-address-support to implement
only the function to read the mac-address from mtd.
Generalize mtd-mac-address-increment function so it can be applied
to any source of of_get_mac_address.
Rename any mtd-mac-address-increment to mac-address-increment.
Rename any mtd-mac-address-increment-byte to mac-address-increment-byte.
This should make simplify the conversion of target to nvmem implementation.

Installation
------------
Web interface:
It is possible to upgrade to OpenWrt via the web interface. However, the
OEM firmware upgrade file is required and a tool to fix the MD5 sum of
the header. This procedure overwrites U-Boot and there is not failsafe /
recovery mode present! To prepare an image, you need to take the header
and U-Boot (i.e. 0x200 + 0x20000 bytes) from an OEM firmware file and
attach the factory image to it. Then fix the header MD5Sum1.
Serial/TFTP:
You can use initramfs for booting via RAM or flash the image directly.
Additional Notes:
If the web interface upgrade fails, you have to open your device and
attach serial console. Since the web upgrade overwrites the boot loader,
you might also brick your device.
In order to flash back to stock, the first header and U-Boot needs to be
stripped from the original firmware.
