b31fc90c14 clk: shmobile: r8a7779: Add CPG/MSTP Clock Domain support
Add Clock Domain support to the R-Car H1 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.

Also update the reg property in the DT binding doc example to match the
actual dtsi, which uses #address-cells and #size-cells == 1, not 2.

7b42a997bf clk: shmobile: r8a7779: Add clocks support
The R8A7779 SoC has several clocks that are too custom to be supported in a
generic driver. Those clocks are all fixed rate clocks with multiplier and
divisor set according to boot mode configuration.

Based on work for R-Car Gen2 SoCs by Laurent Pinchart.
