mt7620 and mt7621 use mt7530 driver, which only accepts "llllw", "wllll",
and "lwlll" values.
According to its switch setup, Mi Router 3G v2 has a WAN port at port 4,
so the correct value should be "llllw".

The node pinctrl0 is already set up in the SOC DTSI files, but
defined again as member of pinctrl in most of the device DTS(I)
files. This patch removes this redundancy for the entire ramips
target.

For some devices, the keys node is named "button". Change name to
match the rest of the target.

INSTALLATION:
Bootloader won't accept any serial input unless "boot_wait" u-boot
environment variable is changed to "on". Vendor firmware (looks like
an illegal OpenWrt fork) won't accept any serial input unless
"uart_en" is set to "1". Tricks to force u-boot to use default
environment do not help as it's restricted in the same way.
With bootloader unlocked the easiest way would be to TFTP the
sysupgrade image or to sysupgrade after loading an initramfs one.
For porting the flash contents were changed externally with an SPI
programmer (after lifting Vcc flash IC pin away from the PCB).
