rampis-mt7621: add support for ZyXEL WSM20

[Kistelini]

(soory for the spam, same as #2962, thought I lost access to my account)

Better known as ZyXEL Multy M1

logread is full of daemon.err hostapd: nl80211: kernel reports: integer out of range, but that should be gone after this is merged.

There are kernel warnings, I have no idea what they mean.

Thanks a lot for testing and adding the device.
Lots of bang for your buck with this one. 30-35€ on Kleinanzeigen. (sometimes 25€ per device if you buy more than one)
Often unused, just resold. It comes with a wall mount.
Telekom as an ISP seems to package these with their contracts but lots of people just resell them instead.

I'll actually open mine soonish and connect via serial to check whether NMBM support is necessary (the dts doesn't have this, yet)

[Djfe]

nvm there's no nmbm to been seen in this oem bootlog
