Kiran KandLuiz Augusto von Dentz 05c200c8f0 Bluetooth: btintel_pcie: Add handshake between driver and firmware
The following handshake mechanism needs be followed after firmware
download is completed to bring the firmware to running state.

After firmware fragments of Operational image are downloaded and
secure sends result of the image succeeds,

1. Driver sends HCI Intel reset with boot option #1 to switch FW image.
2. FW sends Alive GP[0] MSIx
3. Driver enables data path (doorbell 0x460 for RBDs, etc...)
4. Driver gets Bootup event from firmware
5. Driver performs D0 entry to device (WRITE to IPC_Sleep_Control =0x0)
6. FW sends Alive GP[0] MSIx
7. Device host interface is fully set for BT protocol stack operation.
8. Driver may optionally get debug event with ID 0x97 which can be dropped

For Intermediate loadger image, all the above steps are applicable
expcept #5 and #6.

On HCI_OP_RESET, firmware raises alive interrupt. Driver needs to wait
for it before passing control over to bluetooth stack.

future. This patch checks the platform support for reset methods and if
supported uses the same instead of legacy GPIO toggling method.

ACPI firmware supports two types of reset method based on NIC card.
(Discrete or Integrated).

1. VSEC Type - Vendor Specific Extended Capability. Here  BT_EN and
   BT_IF_SELECT lines are driven by a register in PCH cluster. This
   interface is supported on discrete BT solution.

2. WDISABLE2 - In this soluton, W_DISABLE2 pin in M.2 is connected to
   physical GPIO from PCH. The DSM interface shall toggle this to recover
   from  error.
