Bluetooth: Move all mgmt command quirks to handler table
In order to completely generalize the mgmt command handling we need to move away command-specific information from mgmt_control() into the actual command table. This patch adds a new 'flags' field to the handler entries which can now contain the following command specific information: - Command takes variable length parameters - Command doesn't target any specific HCI device - Command can be sent when the HCI device is unconfigured After this the mgmt_control() function is completely generic and can potentially be reused by new HCI channels.
