Subject: [PATCH] Bluetooth: Improve support for Actions Semi ATS2851 based devices
From:   Raul Cheleguini <rcheleguini@google.com>

Precedence: bulk

Add two more quirks to resume the device initialization and basic
operation as the device seems not to support "Read Transmit Power"
and "Set Extended Scan Parameters".

< HCI Command: LE Read Transmit Power (0x08|0x004b) plen 0
> HCI Event: Command Status (0x0f) plen 4
      LE Read Transmit Power (0x08|0x004b) ncmd 1
        Status: Unknown HCI Command (0x01)

< HCI Command: LE Set Extended Scan Parameters (0x08|0x0041) plen 8
        Own address type: Random (0x01)
        Filter policy: Accept all advertisement (0x00)
        PHYs: 0x01
        Entry 0: LE 1M
          Type: Active (0x01)
          Interval: 11.250 msec (0x0012)
          Window: 11.250 msec (0x0012)
> HCI Event: Command Status (0x0f) plen 4
      LE Set Extended Scan Parameters (0x08|0x0041) ncmd 1
        Status: Unknown HCI Command (0x01)
