meta-google: gbmc-bridge: Remove STP support

We no longer have any projects or planned projects that require this
support. We only have single path ethernet as a guarantee now. This
configuration has been causing us some issues on some of our systems and
it will be more stable to just ignore dynamic link configurations and
the software burden of an RSTP stack.
