BT LED Fixed, USB3 Fixed, + Other Fixes

Okay, you don’t need GenericXHCI finally!
just use this kext patch in clover:
Find: C680C800000001
Replace: C680C800000000
Name: AppleUSBXHCI

And voila, USB finally works better as ever, and doesn’t have any bugs
at all anymore!

BT Led now finally checks if BT Device is Off or on… Im not using any
„save last status“ useless crap code…

I fixed a bug, that i have self introduced before^^ you can see the bug
if you change brightness with FN+F keys… you have sth like a buffer…
however… fixed now…

This is now stable DSDT!
