ramips: convert mt76 PCIe NIC EEPROM to NVMEM format for legacy SoCs
This patch converts MT761{0,2,3} PCIe WiFi calibration data to NVMEM
format for legacy Ralink SoCs (MT7620 and Mt7628). The EEPROM size of
the MT7610 and MT7612 is 0x200. there are only three devices uses
MT7613 NIC, ASUS RT-AC1200 V2, COMFAST CF-WR758AC V2 and Keenetic
KN-1613. The EEPROM size of them is 0x4da8.

9968a909c2 Revert "ramips: increase spi-max-frequency for ipTIME mt7620 devices"
This reverts commit 13a185bf8a.

There was a report that one A1004ns device fails to detect its flash
chip correctly:

[    1.470297] spi-nor spi0.0: unrecognized JEDEC id bytes: e0 10 0c 40 10 08
[    1.484110] spi-nor: probe of spi0.0 failed with error -2

It also uses a different flash chip model:
* in my hand: Winbond W25Q128FVSIG (SOIC-8)
* reported: Macronix MX25L12845EMI-10G (SOP-16)

Reducing spi-max-frequency solved the detection failure. Hence revert.

13a185bf8a ramips: increase spi-max-frequency for ipTIME mt7620 devices
This commit increases the hardware SPI frequency from 24.2MHz to 48.3MHz.

[    5.314163] m25p80 spi0.0: speed: 24166666/40000000, rate: 8, prescal: 2, loops: 226
[    5.076323] m25p80 spi0.0: speed: 48333333/50000000, rate: 4, prescal: 1, loops: 162

`time cat /dev/mtd2 >/dev/null` is reduced from 5.64s to 4.36s on A104ns,
and from 11.39s to 8.81s on A1004ns.

38bdfcdb87 ramips: add support for ipTIME A104ns
ipTIME A104ns is a 2.4/5GHz band AC750 router, based on MediaTek MT7620A.

Specifications:
- SoC: MT7620A
- RAM: DDR2 64MB
- Flash: SPI NOR 8MB
- WiFi:
  - 2.4GHz: SoC internal
  - 5GHz: MT7610EN
- Ethernet: 5x 10/100Mbps
  - Switch: SoC internal
- USB: 1x 2.0
- UART:
  - J2: 3.3V, TX, RX, GND (3.3V is the square pad) / 57600 8N1

Installation via web interface:
1.  Flash **initramfs** image through the stock web interface.
2.  Boot into OpenWrt and perform sysupgrade with sysupgrade image.

Revert to stock firmware:
1.  Perform sysupgrade with stock image.

In contrast to to-be-supported A1004ns, the A104ns has no usable
value in 0x1fc40 (uboot), so wan_mac needs to be calculated.
Also note that GPIOs for the LEDs really are inverted compared to
the A1004ns.

[moved state_default to device DTS, reordered properties in wmac,
added comment about wan_mac and LED GPIOs]
