[PATCH RFC 1/6] dt-bindings: dma: qcom,gpi: Retire passing the protocol ID

[Konrad Dybcio]

From: Konrad Dybcio <konrad.dybcio@xxxxxxxxxxxxxxxx>

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.
