[PATCH v2 0/2] Bluetooth: add hardware rfkill handling

[Sai Teja Aluvala <aluvala.sai.teja@intel.com>]

This series adds hardware rfkill handling for the Intel PCIe transport and
the Bluetooth-side notification path.

The resulting flow is:

  transport hardware event
    -> hci_rfkill_set_hw_state()
    -> rfkill hardware state
    -> hdev->rfkill_block work
    -> HCI_RFKILLED state and device power handling

For Intel PCIe controllers, the series adds GP2 and HW_RFKILL MSI-X
handling, IPC_CONTROL doorbell synchronization, delayed state checking,
reset/shutdown/remove lifecycle handling, and notification of the
generic HCI rfkill layer.

Compared with v1, this version drops the Bluetooth-specific debugfs test
hook, the redundant hdev->rfkill pointer-clear patch, and the separate
RFKILL-core helper dependency. The real btintel_pcie hardware event path
and HCI notification interface are retained.

    events
