The JHB100 SoC includes CRG (Clock and Reset Generator) for multiple
subsystems:

The JHB100 SoC is divided into multiple subsystems, and basically
each subsystem includes a CRG(Clock and Reset Generator):
- sys0crg/sys1crg/sys2crg/
- per0crg/per1crg/per2crg/per3crg/
- voutcrg
- vcecrg
- gpu0crg/gpu1crg
- cpucrg
- usbcrg
- host0crg/host1crg
- pcierpcrg
- husb0crg/husb1crg
- husbcmncrg
- husbd0crg/husbd1crg
- npucrg

In the current series, we will only add the following CRG:
- sys0crg/sys1crg/sys2crg/
- per0crg/per1crg/per2crg/per3crg/

The remaining CRG will be implemented in future series.

This series depends on the series:
https://lore.kernel.org/all/20260402084019.440708-1-changhuang.liang@starfivetech.com/
and it has been tested on the StarFive JHB100 EVB-1.
