Broadcom BCM20702A0 and HSP/HFP functionality

Hello,

I've been working on quite a few yet to be released devices that use the
BCM20702A0 chip but can't operate in HSP or HFP mode.

I was wondering if anyone has been able to get head set profile working
with that chip.

If not, I'm somewhat new to the bluetooth stack and I'd be interested in
debugging tips.

I've attached timestamped hcidump, pulseaudio, bluetoothd, and
dbus-monitor output to the following bug:

Thanks!
