evcc: go-e charger - 1p setting ignored since 0.112

Describe the bug

I am having a “classic” go-e charger, which is physically connected on 3phases, but I am using a 1p charging cable so to being able to load solar power with low production in winter.

Therefore I have hardcoded the loadpoint to “1 phase” and it was working fine until the recent update.

I suppose that this PR breaks it: https://github.com/evcc-io/evcc/pull/5764 by overriding the loadpoint setting with something derived from connected voltages.

Steps to reproduce

Start evcc in “pv” mode with loadpoint 1p
Check the logs

Configuration details

loadpoints:
  - title: go-e # display name for UI
    charger: goe # charger
    mode: pv
    phases: 1 # ev phases (default 3)
    enable: # pv mode enable behavior
      delay: 30s # threshold must be exceeded for this long
      threshold: 0 # minimum export power (W). If zero, export must exceed minimum charge power to enable
    disable: # pv mode disable behavior
      delay: 10m # threshold must be exceeded for this long
      threshold: 500 # maximum import power (W)

After manual switch to "minpv" mode, the problem fixes itself, as it detects that only 1p is working:

Super dass wir eine Lösung gefunden haben ohne den anderen Anwendern die automatische Umschaltung weg nehmen zu müssen 😃

phases am Loadpoint gibt genau die netzseitig anliegenden Phasen an.

@premultiply I disagree insofar as that it is also the phases the charger (!) will use for charging. We have not considered the cable scenario. We may of course chose to ignore it.

Optionally using a 1p cable is a perfectly viable scenario that the detection is breaking. Even if user sets 1 on loadpoint (which is correct for the cable) we would change that to 3 which is not what will happen. Also, we don’t have an API for setting the value on vehicle level, so we’re forcing a wrong update on the user.
