[PATCH v1 1/2] dt-bindings: net: bluetooth: ti: Add property for enhanced SCO setup erratum

[Stefano Radaelli]

From: Stefano Radaelli <stefano.r@xxxxxxxxxxxxx>

Some Bluetooth controller/firmware combinations advertise support for the
HCI Enhanced Setup Synchronous Connection command but do not handle it
correctly for SCO setup in certain configurations (e.g.
BT_VOICE_TRANSPARENT/mSBC). This results in SCO audio not working unless
the enhanced setup path is avoided.

Add an optional boolean property, ti,no-enhanced-setup-sync-conn, to
describe this controller limitation.
