[PATCH v4 0/2] Bluetooth: Add btrealtek data struct and improve SCO sound quality of RTK chips

[hildawu]

From: Hilda Wu <hildawu@xxxxxxxxxxx>

Add btrealtek data struct and use definition of vendor flags to manage
the specific chip.

The Bluetooth: btusb: Ignore zero length of USB packets on ALT 6 for
specific chip need to transmit mSBC data continuously without the
zero length of USB packets.

---
Changes in v4:
 - Since the original 0002 patch has no dependency with this 0001 patch.
   So let the 0002 patch submit independent.

Changes in v3:
 - Use the vendor function to replace btus_recv_isoc.
 - For ignore_usb_alt6_packet_flow, manage the common flag by the vendor private flag.

Changes in v2:
 - Set the proper priv_size to hci_alloc_dev_priv().
 - Separate commits for functions.

Thank you for your review and suggestions.
