Re: [RFC PATCH v4 1/5] Bluetooth: Add mgmt op set_wake_capable

When the system is suspended, only some connected Bluetooth devices
cause user input that should wake the system (mostly HID devices). Add
a list to keep track of devices that can wake the system and add
a management API to let userspace tell the kernel whether a device is
wake capable or not. For LE devices, the wakeable property is added to
the connection parameter and can only be modified after calling
add_device.

Changes in v4: None
Changes in v3:
* Added wakeable property to le_conn_param
* Use wakeable list for BR/EDR and wakeable property for LE

Changes in v2: None
