clk: shmobile: rz: Add CPG/MSTP Clock Domain support
Add Clock Domain support to the RZ 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.
