Bluetooth: Add bt_printk
Add a local logging function to emit bluetooth specific messages. Using vsprintf extension %pV saves code/text space. Convert the current BT_INFO and BT_ERR macros to use bt_printk. Remove __func__ from BT_ERR macro (and the uses). Prefix "Bluetooth: " to BT_ERR Remove __func__ from BT_DBG as function can be prefixed when using dynamic_debug.
