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

Commit Message

Dwivedi, Avaneesh Kumar (avani) Dec. 15, 2016, 12:05 p.m. UTC

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.
