[PATCH v4 0/3] reset: cix: add support for cix sky1 resets

[Xueyuan Chen]

This patch series adds support for the System Reset Controller (SRC)
found on the CIX Sky1 SoC. The SRC provides reset capabilities to various
peripherals across the S0 and S5 domains.

Changes in v4:
- Restored the 'syscon' architecture to properly describe the SRC as a 
  unified memory region, addressing DT review feedback from Conor Dooley on v3.
- Replaced the fragmented 'reg' items in the YAML bindings and DTS with 
  unified contiguous memory regions (e.g., 0x16000000 and 0x04160000).
- Refactored the driver to drop independent ioremap logic. It now cleanly 
  fetches the regmap via syscon_node_to_regmap to prevent resource conflicts.
- Xueyuan Chen took over the patchset for architectural refactoring.

Changes in v3:
- Passed dts build checks (dt_binding_check, CHECK_DTBS).
- Removed initial syscon attempt (reverted in v4 for the correct architecture).
