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.
With allyesconfig:
