Subject: [PATCH] Avoid usb detection at _FT8726 touchscreen driver

WHAT: This changes restrict the recent impletementation of usb detection
        at focaltech fingerprint driver so it does dot affect _FT8726
WHY:  At current implementation of usb detection, _FT8726 causes a
      kernel panic when the USB cable is connected. _FT8726 cannot set
      the register that fts_mcu_usb_detect_set expects it to have, so it
      holds a mutex, fails to set the register and panics at
      ___might_sleep. The support of us detect is handled by
      FTS_USB_DETECT_EN, so disable it for _FT8726
