Bluetooth: btusb: Make the CSR clone chip force-suspend workaround more generic
Turns out Hans de Goede completed the work I started last year trying to improve Chinese-clone detection of CSR controller chips. Quirk after quirk these Bluetooth dongles are more usable now. Even after a few BlueZ regressions; these clones are so fickle that some days they stop working altogether. Except on Windows, they work fine. But this force-suspend initialization quirk seems to mostly do the trick, after a lot of testing Bluetooth now seems to work *all* the time. The only problem is that the solution ended up being masked under a very stringent check; when there are probably hundreds of fake dongle models out there that benefit from a good reset. Make it so.
