i also want to take care of those dwc2 warnings, which might need some
additional DT settings:

dwc2 20980000.usb: 256 invalid for host_nperio_tx_fifo_size. Check HW
dwc2 20980000.usb: 512 invalid for host_perio_tx_fifo_size. Check HW
dwc2 20980000.usb: Specified GNPTXFDEP=1024 > 32

What LED change do you expect?

Lubomir's suggestion is HIGH_ACTIVE which is more userfriendly because of the
missing PWR LED.
Changing to LOW_ACTIVE would be more stringent according to all the other RPis.

Btw the DTS for the RPi Zero has been dropped in downstream.
