fix(ewelink): add Correct manufacturer display

[sonofftaotaoliu]

Hi there, I'm a member of the Sonoff team, and I'm currently working on updating the manufacturer display for some of our sensors on eWeLink. I've already verified the changes locally and they're all set to go. Could you please help me merge these updates, KK? Thank you so much for your support!
