Bluetooth: Perform a power cycle when receiving hardware error event
When receiving a HCI Hardware Error event, the controller should be
assumed to be non-functional until issuing a HCI Reset command.
The Bluetooth hardware errors are vendor specific and so add a
new hdev->hw_error callback that drivers can provide to run extra
code to handle the hardware error.
After completing the vendor specific error handling perform a full
reset of the Bluetooth stack by closing and re-opening the transport.
