Add vibration motor to Powkiddy V90

[360fun]

Hi and thank you for the amazing work behind this firmware! 🤖

After I bought the Powkiddy V90 I discovered (https://youtu.be/nWTRpo2fzJI) that some consoles have a vibration motor and others don't (like mine 😢 ). I was wondering if it can be soldered to the motherboard since the software (and hopefully the circuit lines) are already there. I don't know much about circuits so it's just a guess/hope. 🤞

I couldn't find images about internals with the motor to compare, but in these images that white circle with 2 nearby soldering points looks like the perfect spot:

Any expert could confirm/deny this guess?

Looks like I was right! 🥳 I will check with a tester if I get voltage when vibration is activated, thanks!
