[PATCH v1 0/6] Add System-0 CRG for JHB100 SoC

[Changhuang Liang]

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

This is a split of the previously sent large series [1].
The original series had too many patches, and there was a lot of
similar logic among the patches. To reduce the burden of repeating
similar comments and reviews, the original series of patches was
split up and a new series was established.

This series is based on the clk-next branch.

Changes since previous submission:
- Change RESET_STARFIVE_JHB100 from select to imply.
- Fix the external clock index to JH71X0_EXT_CLK_FLAG, and add
  JH71X0_EXT_CLK(_n) to define the external clock index.
- Remove CLK_IS_CRITICAL usage in sys0.
- Add a static_assert to check at compile time whether the internal
  clock and the external clock overlap in sys0.
- Remove 'power_domain" from 'struct jh71x0_crg_domain_info'.
- Register the reset device using devm_auxiliary_device_create().
- Obtain 'struct jh71x0_reset_adev *' via dev_get_platdata().
- Streamline the reset patch, keeping only the sys0 part.
