[PATCH] Bluetooth: Fix issue with Actions Semi ATS2851 based devices

[Marcel Holtmann]

Their devices claim to support the erroneous data reporting, but don't
actually support the required commands. So blacklist them and add a
quirk.

This device appears to not support HCI_OP_LE_READ_TRANSMIT_POWER,
either. I get this with the above patch applied:

> Bluetooth: hci0: Opcode 0x204b failed: -56

Then it fails to register as a functioning interface, and bluez thinks
bluetooth is turned off.

In my case, it's a Techkey long range adapter, which is probably a similar
model to the above mentioned Ugreen device, except that it also has a
detachable pole antenna.

So sorry for the noise, I didn't notice there was a new patch revision.
