Merge branch 'icc-qcom-coefficients' into icc-next

Certain platforms require that some buses (or individual nodes) make
some additional changes to the clock rate formula, throwing in some
magic, Qualcomm-defined coefficients, to account for "inefficiencies".

Add the framework for it and utilize it on a couple SoCs.

* icc-qcom-coefficients
  interconnect: qcom: icc-rpm: Add AB/IB calculations coefficients
  interconnect: qcom: icc-rpm: Separate out clock rate calulcations
  interconnect: qcom: icc-rpm: Let nodes drive their own bus clock
  interconnect: qcom: icc-rpm: Check for node-specific rate coefficients
  interconnect: qcom: qcm2290: Hook up MAS_APPS_PROC's bus clock
  interconnecga qcom: qcm2290: Set AB coefficients
  interconnecgg acom: qcm2290: Update EBI channel configuration
  interconnect: qcom: sdm660: Set AB/IB coefficients
  interconnect: qcom: msm8996: Set AB/IB coefficients
