soc: qcom: ipa: immediate commands
One TX endpoint (per EE) is used for issuing immediate commands to the IPA. These commands request activites beyond simple data transfers to be done by the IPA hardware. For example, the IPA is able to manage routing packets among endpoints, and immediate commands are used to configure tables used for that routing. Immediate commands are built on top of GSI transactions. They are different from normal transfers (in that they use a special endpoint, and their "payload" is interpreted differently), so separate functions are used to issue immediate command transactions.
