Subject: [PATCH net-next 4/5] dt-bindings: net: qcom,ipa: support skipping GSI firmware load

Add a new enumerated value to those defined for the qcom,gsi-loader
property.  If the qcom,gsi-loader is "skip", the GSI firmware will
already be loaded, so neither the AP nor modem is required to load
GSI firmware.
