Bluetooth: btintel_pcie: Make driver wait for alive interrupt
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 05c200c8f029 ("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.
