Subject: [PATCH v3 0/4] Introduce LLCC v6 used on the SM8750 SoCs

Add documentation and functionality for LLCC v6 used on
the SM8750 SoCs. LLCC v6 rearranges several registers and offsets
and supports slice IDs over 31, so new functionality is necessary
to program and use LLCC v6.

---
Changes in v3:
- Removed some unused variables.
- Added parent/child grouping features to v6
- Updated cache data table with up-to-date configurations
- Link to v2: https://lore.kernel.org/r/20250304-sm8750_llcc_master-v2-0-ae4e1949546e@quicinc.com

Changes in v2:
- moved v6 offsets into cfg struct
- reverse xmas-treed variable declarations & removed unused
- removed unneeded skip_llcc_cfg branch in v6
- updated some macros to use BITS, GENMASK, FIELD_PREP
- moved LLCC_* definitions to appropriate patch
- updated sm8750 slice data struct to match updated standard
- fixed style on dt node
- note: did not add cleanup patch to use bitfields
- Link to v1: https://lore.kernel.org/r/20250113-sm8750_llcc_master-v1-0-5389b92e2d7a@quicinc.com
