In the current btintel_pcie driver implementation, when an interrupt is
received, the driver checks for the alive cause before the TX/RX cause.
Handling the alive cause involves resetting the TX/RX queue indices.
This flow works correctly when the causes are mutually exclusive.
However, if both cause bits are set simultaneously, the alive cause
resets the queue indices, resulting in an event packet drop and a
command timeout. To fix this issue, the driver is modified to handle all
other causes before checking for the alive cause.
Test case:

This patch implements _suspend() and _resume() functions for the
Bluetooth controller. When the system enters a suspended state, the
driver notifies the controller to perform necessary housekeeping tasks
by writing to the sleep control register and waits for an alive
interrupt. The firmware raises the alive interrupt when it has
transitioned to the D3 state. The same flow occurs when the system
resumes.

The firmware raises an alive interrupt upon sending the HCI_RESET or
BTINTEL_HCI_OP_RESET command. As part of handling the reset command,
firmware initializes the hardware and data path and raises the alive
interrupt. Upon receiving the alive interrupt, the driver must enable
the data path and grant RX buffers to the firmware before sending any
commands.
The alive context maintained in the driver must be updated before
sending BTINTEL_HCI_OP_RESET or HCI_OP_RESET to prevent a potential race
condition where the context is also updated in the threaded IRQ.
The issue was observed in a stress reboot usecase (1/25) using "sudo
reboot" command where the firmware download was failing as the driver
was not granting RX buffer to firmware due to race condition.

The firmware raises an alive interrupt upon receiving the HCI_RESET or
BTINTEL_HCI_OP_RESET (Intel reset - 0xfc01) command. This change fixes
the driver to properly wait for the alive interrupt to avoid driver
sending commands to firmware before it is ready to process.
For details on the handshake between the driver and firmware, refer to
commit 05c200c8f0 ("Bluetooth: btintel_pcie: Add handshake between
driver and firmware").
As the driver needs to handle two interrupts for HCI_OP_RESET and
BTINTEL_HCI_OP_RESET, the firmware ensures that the TX completion
interrupt is always followed by the alive interrupt.

Due to a hardware issue, there is a possibility that the driver may miss
an MSIx interrupt on the RX/TX data path. Since the TX and RX paths are

approach applies to the RX path.

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.

for it before passing control over to bluetooth stack.
