ath79: fix ethernet setup for some qca953x devices

On Comfast CF-E130N v2 and Mikrotik LHG HB board, the config
found in DTS appears to be strange:

- eth0 has "syscon","simple-mfd" set although it's not enabled
- eth1 is enabled redundantly (already "okay" in qca953x.dtsi)
- phy-handle is set for eth1 in DTS although it has a fixed-link
  in qca953x.dtsi

This seems like a copy-paste gone wrong. Remove the named options.

Run-tested on MikroTik LHG 2.
