Thunderbolt 3 Hotplug Support (Enhancement)

[RegDogg]

I'm a newbie at GitHub so this isn't much of an issue. (I don't know how to do a pull request)

But I recently tinkered with this archive and used a Thunderbolt 3 SSDT Patch.

Below is the listed file you can use.
SSDT-TB3.zip

Another thing with the TB3 SSDT Patch is you don't need Thunderbolt BIOS Assist enabled, as I find it to crap out and cause the Thunderbolt chipset to become invisible in macOS Catalina

Test result: TB3 hotplug works well with it, however, MacOS will crash and restart when I switch from one TB3 to another TB3. Thanks

I tried it but it doest work for me. Do i need to config something in the bios?

This is relevant to post here; there's a well known issue with these generation of thinkpads where the firmware on the TB3 chip completely bricks (on all OSs, completely hardware, not drivers or any OS stuff). So my machine's stuck at their repair depot getting fixed right now. I'll try this hotplug support when I can.

However, I was using a tb3 EGPU and was actually able to hotplug tb3 on a FEW occasions (but it didn't work everytime). Super odd.

I'll report back when I get my machine back. @shangjun2x would you be so kind as to provide a branch name that you created or create one for me to test?
