You can find the pullups in the downstream device tree source file.  Or
 at least I think that's what's setting up the pullups. Although if you
are detecting it, it might be correct.

I know they made a patch for bluez that might be part of it.  I also
know the Bluetooth module used in the RPI 3 isn't that great.  It's a
serial attached module for all that's worth.
