From: Bartosz Golaszewski <bartosz.golaszewski@xxxxxxxxxx>
Add the Bluetooth node for RB5 as well as its dependencies in the form
of the uart6 -> serial1 alias and the pin function for the Bluetooth
enable GPIO.
Signed-off-by: Bartosz Golaszewski <bartosz.golaszewski@xxxxxxxxxx>

v1 -> v2:
- squash the three device-tree patches into one
- as we're only using a single pin for the BT enable GPIOs, there's no
need for a separate named node
- change the naming convention for regulators to follow the bindings
