remoteproc: qcom: Compatible string based private resource initialization.

Browse Source 
MSS rproc loader need chip specific resources initialization during probe
to load and boot modem firmware, this need compatible string based
differentiation in resources to be initialized. This patch add and provide
a template struct whose fields represent all those resources which are
needed to load and boot modem fw and which may differ from chip to chip.
This patch also add new compatible string for msm8916, msm8974 platform.
