ARM: dts: pandaboard es: add bluetooth uart for HCI
The wl271 bluetooth uart is connected to uart2. Setup a serdev uart child and separate bluetooth and uart2 pinmux from wl12xx pinmux to better group the pins and muxes. Signed-off-by: H. Nikolaus Schaller <hns@goldelico.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
