f1c9afd801 ramips: mt7621-dts: mux phy0/4 to gmac1
Mux the MT7530 switch's phy0/4 to the SoC's gmac1 on devices where RGMII2
pins are available. This achieves 2 Gbps total bandwidth to the CPU using
the second RGMII.

The ports called "wan" are muxed where possible. On a minority of devices,
this is not possible. Those cases:

mt7621_ampedwireless_ally-r1900k.dts: lan3
mt7621_ubnt_edgerouter-x.dts: eth0
mt7621_gnubee_gb-pc1.dts: ethblue
mt7621_linksys_re6500.dts: lan1
mt7621_netgear_wac104.dts: lan4
mt7621_tplink_eap235-wall-v1.dts: lan0
mt7621_tplink_eap615-wall-v1.dts: lan0
mt7621_ubnt_usw-flex.dts: lan1

The "wan" port is just what the vendor designated on the board/plastic
chasis of the device. On a technical level, there is no difference between
a lan and wan port on MT7621AT, MT7621DAT and MT7621ST SoCs. Prefer
connecting to WAN via the port described above for these devices to benefit
the feature brought with this patch.

mt7621_d-team_newifi-d2.dts cannot benefit this feature, although it looks
like it should, because the rgmii2 pins are wired to unused components.

Tested on a range of devices documented on the GitHub PR.

b8168f4716 ramips: add support for D-Link DIR-853-R1
This PR adds support for router D-Link DIR-853-R1

Specifications:

    SoC: MT7621AT
    RAM: 128MB
    Flash: 16MB SPI
    WiFi: MT7615DN (2.4GHz+5Ghz) with DBDC (This mode allows this
      single chip act as an 2x2 11n radio and an 2x2 11ac radio at the
      same time)
    LAN: 5x1000M
    LEDs Power Blue+Orange,Wan Blue+Orange,WPS Blue,"2.4G"Blue, "5G" Blue
    USB Blue
    Buttons Reset,WPS, Wifi

MAC addresses:

|Interface   |        MAC      |    Factory  |Comment
|------------|-----------------|-------------|----------------
|WAN sticker |C4:XX:XX:6E:XX:2A|             |Sticker
|LAN         |C4:XX:XX:6E:XX:2B|             |
|Wifi (5g)   |C4:XX:XX:6E:XX:2C|0x4          |
|Wifi (2.4g) |C6:XX:XX:7E:XX:2C|             |
|            |                 |             |
|            |C4:XX:XX:6E:XX:2E|0x8004 0xe000|
|            |C4:XX:XX:6E:XX:2F|0xe006       |

The increment of the 4th byte for the 2.4g address appears to vary.
Reported cases:

       5g                 2.4g         increment
 C4:XX:XX:6E:XX:2C  C6:XX:XX:7E:XX:2C  0x10
 f4:XX:XX:16:XX:32  f6:XX:XX:36:XX:32  0x20
 F4:XX:XX:A6:XX:E3  F6:XX:XX:B6:XX:E3  0x10

Since increment is inconsistent and there is no obvious pattern
in swapping bytes, and the 2.4g address has local bit set anyway,
it seems safer to use the LAN address with flipped byte here in
order to prevent collisions between OpenWrt devices and OEM devices
for this interface. This way we at least use an address as base
that is definitely owned by the device at hand.

Flashing instruction:

The Dlink "Emergency Room"

Connect your client computer to LAN1 of the device
Set your client IP address manually to 192.168.0.101 / 255.255.255.0.
Then, power down the router, press and hold the reset button, then
re-plug it. Keep the reset button pressed until the internet LED stops
flashing
Call the recovery page or tftp for the device at http://192.168.0.1
Use the provided emergency web GUI to upload and flash a new firmware to
the device.

[commit title/message improvements, use correct label MAC address,
 calculate MAC addresses based on 0x4, minor DTS style fixes, add
 uart2 to state_default, remove factory image, add 2.4g MAC address,
 use partition DTSI, add macaddr comment in DTS]
