[PATCH 1/2] dt-bindings: net: broadcom-bluetooth: Add property for autobaud mode

[Hakan Jansson <hakan.jansson@infineon.com>]

Some devices (e.g. CYW5557x) require autobaud mode to enable FW loading.
Autobaud mode can also be required on some boards where the controller
device is using a non-standard baud rate when first powered on.

This patch adds a property, "brcm,uses-autobaud-mode", to enable autobaud
mode selection.
