From c0c9a631e7ca58cc31aafb14920c559552d3b810 Mon Sep 17 00:00:00 2001

Subject: [PATCH] overlays: pi3-disable-bt: Clear out bt_pins node
The pi3-disable-bt overlay does not (and cannot) delete the bt_pins
node, but emptying its properties (including brcm,pins) is a way of
signalling to the hciuart systemd service that Bluetooth has been
disabled.
