Subject: [PATCH v1 3/4] Bluetooth: btusb: Enable MSFT extension for Intel controllers

The Intel JeffersonPeak, HarrisonPeak and CyclonePeak Bluetooth
controllers support the Microsoft vendor extension and they are using
0xFC1E for VsMsftOpCode.

< HCI Command: Vendor (0x3f|0x001e) plen 1
        00
> HCI Event: Command Complete (0x0e) plen 15
      Vendor (0x3f|0x001e) ncmd 1
        Status: Success (0x00)
        00 3f 00 00 00 00 00 00 00 01 50

The following test step was performed.
- Boot the test devices with HarrisonPeak and verify INFO print in
dmesg.
