Fix 2FA issue

[paul159321]

I found that login_step1 was causing repeated 2FA authentication requests, so I skipped it and modified the way to obtain the serviceToken. For me, it's now possible to log in to the account normally.

Hello! Thank you for the code modifications. I wanted to ask if I can simply overwrite the original file with your modified xiaomi_cloud.py file for it to work properly?

Yes.After you overwrite the file,you need to restart your homeassistant.

After I overwrote the file and then restarted HAOS, I was able to log into my account normally. However, after successfully logging in, when I tried to add an entry, I didn't see the gateway under my account. Why is this? Do you know the reason?
Thank you once again for your and the author's efforts!

Hello 👋
First of all, thank you for your continued work on this project! 🙌

I noticed that the hass-xiaomi-miot project has addressed Xiaomi account login issues in their recent PR #2429, specifically through updates to the xiaomi_cloud.py implementation.

Would you be open to incorporating similar fixes here? I'd be happy to help draft a PR if this approach aligns with the project's direction.Thanks again! 🙌
