clk: shmobile: rcar-gen2: Add CPG/MSTP Clock Domain support
Add Clock Domain support to the R-Car Gen2 Clock Pulse Generator (CPG)
driver using the generic PM Domain. This allows to power-manage the
module clocks of SoC devices that are part of the CPG/MSTP Clock Domain
using Runtime PM, or for system suspend/resume.
SoC devices that are part of the CPG/MSTP Clock Domain and can be
power-managed through an MSTP clock should be tagged in DT with a proper
"power-domains" property.
