Working Battery/Trackpad/Volume keys

[backdash756]

Thank you for the great work @badstorm

I really don't know how I did it, but after a few unsuccessful touchscreen attempts with VoodooI2c.kext and VoodooI2cGoodix.kext, the following works perfectly:

• Battery status
• Trackpad recognized in the system settings and fully functional
• Volume up/down buttons work now.

Maybe you can draw conclusions from my EFI folder:
