[PATCH v5 00/11] Bluetooth: btintel: Refactoring setup routines

From: Tedd Ho-Jeong An <redacted>

This patch set refactors the multiple setup routines for various Intel devices
to a combined single entry. Here are the highlight of the changes:

0. Sync with the current tip of the master:
   acd5aea400 ("Bluetooth: btusb: Add valid le states quirk")

1. Updated hci_alloc_dev() to allocate the hdev object with an extra buffer
   for the private data. btintel introduces the btintel_data struct and
   store it to the private data in hdev object.

2. Added a single entry for setup and shutdown and uses the
   HCI_Intel_Read_Version command to identify the device, instead of
   relying on the USB VID and PID.

   Also, it uses the new format of HCI_Intel_Read_Version command for
   legacy ROM and legacy bootloader devices. Luckly legacy devices
   support the new format.

3. Keep the state of bootloader in btintel object. The bootloader state
   is agnostic to the transport type, so btintel uses the btintel_data
   to keep track of the state in the private data section in hdev.

4. After identifying the setup type for the device, it uses the
   correspond setup routines based on the setup type, and the setup
   routines were moved from btusb to btintel.
   However, actual work for the setup routines were not changed or very
   minimal.

5. Since many functions were moved from btusb to btintel, clean up the
   exported functions and make them static if possible.

6. From the JfP/ThP, the operational firmware support the new TLV based
   HCI_Intel_Read_Version command, which confues the usage during the
   setup routine. So, the check for firmware variant of those legacy
   bootloader sku is added to use the legacy bootloader setup call.

Changes in v5
- Added hci_alloc_dev_priv() to allocate the hdev with private data.
  This will also minimize the changes to other code that uses
  hci_alloc_dev().

- Minor fixes with checkpatch result.
