First things first, I do not have access to the specs nor the schematics, so a
lot of this was done via guess work, looking at the acpi tables, and looking at
how a similar device (wcn6750) was added.
The 5th revision addresses comments from Luiz about the Bluetooth driver, as
well as Konrad's comments on the dts file.
The end result is that we do have a working device, but not entirely reliable.
Hopefully by getting this out there, people who do have access to the specs or
schematics can see where the improvements or fixes need to come.
There are a few things that I am not sure why they happen, and don't have the
knowledge level to figure out why they happen or debugging it.

Bluetooth: hci0: QCA setup on UART is completed
I do not know why the Frame assembly failed, and modprobe -r hci_uart and then
modprobe hci_uart does not show the same Frame assembly failed.
The BD Address also seems to be incorrect, and I'm not sure what is going on
there either.
Testing was done by connecting a Razer Orochi bluetooth mouse, and using it, as
well as connecting to and using an H2GO bluetooth speaker and playing audio out
via canberra-gtk-play as well as a couple of YouTube videos in a browser.
The mouse only seems to work when < 2 ft. from the laptop, and for the speaker, only
"A2DP Sink, codec SBC" would provide audio output, and while I could see that
data was being sent to the speaker, it wasn't always outputting, and going >
4ft. away, would often disconnect.
