From: Konrad Dybcio <konrad.dybcio@oss.qualcomm.com>

This is a software construct that has no business being expressed in
dt-bindings. Drivers can be constructed to retrieve the protocol ID at
runtime or hardcode them per protocol.

Remove it, as a pre-requisite for further simplifying the GENI
bindings.
