Johan Hedberg 6cafcd9595 Bluetooth: btusb: Detect new kind of counterfeit CSR controllers
Controllers claiming to be CSR with LMP subversion 0x0c5c don't
actually seem to be authentic CSR controllers. They also don't have
their USB bcdDevice value matching the LMP subversion like all other
CSR controllers:

HCI:

> HCI Event: Command Complete (0x0e) plen 12
      Read Local Version Information (0x04|0x0001) ncmd 1
        Status: Success (0x00)
        HCI version: Bluetooth 2.0 (0x03) - Revision 3164 (0x0c5c)
        LMP version: Bluetooth 2.0 (0x03) - Subversion 3164 (0x0c5c)
        Manufacturer: Cambridge Silicon Radio (10)

These controllers also have the HCI_Read_Stored_Link_Key command
broken so it's important the right quirk is set for them.
