Hi Miao-chen,

This adds a bit mask of driver_info for Microsoft vendor extension and
indicates the support for Intel 9460/9560 and 9160/9260. See
https://docs.microsoft.com/en-us/windows-hardware/drivers/bluetooth/
microsoft-defined-bluetooth-hci-commands-and-events for more information
about the extension. This was verified with Intel ThunderPeak BT controller
where msft_vnd_ext_opcode is 0xFC1E.

Changes in v3:
- Create net/bluetooth/msft.c with struct msft_vnd_ext defined internally
and change the hdev->msft_ext field to void*.
- Define and expose msft_vnd_ext_set_opcode() for btusb use.
- Init hdev->msft_ext in hci_alloc_dev() and deinit it in hci_free_dev().

so I spent some cycles on thinking about on how we can have this nice and cleanly without putting too much into the core stack or hci_dev. I took your patches and converted them a little bit into how I would do it. Please have a look.

Thanks for brainstorming the framework. I will address your suggestion
in v4 shortly.

Regards,
Miao
