Add support for QCOM GDSCs

GDSCs (Global Distributed Switch Controllers) control switches that supply power to an on-chip power domain and hence can be programmed in SW to safely power collapse and restore power to the respective PDs. They are part of a considerable number of recent QCOM SoCs (This series adds support for msm8974, msm8916 and apq8084 devices) and are part of the Clock control block.

The series implements support for GDSC using the genpd framework modelling these as SW controllable power domains.

8916 support has a dependency on the Global Clock controller support [1] posted by Georgi Djakov.
