[PATCH v5 1/7] remoteproc: qcom: Add private resource struct and new compatible.

[Avaneesh Kumar Dwivedi]

Make provison for private resource specific to each compatible,
so a private resource struct is introduced which will house clock,
regulator etc. related info corresponding to each compatible to use
later to initialize hardware. Also add new compatible in documentation.
