Subject: [PATCH v6 0/2] Bluetooth: btusb: Add protocol support for MediaTek USB devices

From: Sean Wang <sean.wang@...iatek.com>

v6:
* fix drivers/bluetooth/btusb.c:2683:2-3: Unneeded semicolon based reported by [1]

v5:
* rebase to latest code base.
* change the subject prefix.
* change the place the firmware located at.

v4:
* use new BTUSB_TX_WAIT_VND_EVT instead of BTMTKUSB_TX_WAIT_VND_EVT
  to avoid definition conflict and to fix bulk data transfer fails.
* use the bluetooth-next as the base

v3:
add fixes and enhancements based on [1]
* reuse flags and evt_skb btusb already had
* add ctrl_anchor and the corresponding handling
* apply mtk specific recv function
* add more comments explaining wmt ctrl urbs behavior.

v2:

add fixes and enhancements based on [1]
* include /sys/kernel/debug/usb/devices portion in the commit message.
* turn default into n for config BT_HCIBTUSB_MTK in Kconfig
* only add MediaTek support to btusb.c
* drop cmd_sync callback usage
* use __hci_cmd_send to send WMT commands
* add wait event handling similar to what is being done in btmtkuart.c
* submit a control IN URB similar to interrupt IN URB on demand for the WMT
  commands during setup 
* add cosmetic changes

v1:

This adds the support of enabling MT7668U and MT7663U Bluetooth
function running on the top of btusb driver. The patch also adds
a newly created file mtkbt.c able to be reused independently from
the transport type such as UART, USB and SDIO.
