StarFive's StarLink Cache Controller flush/invalidates cache using non-
conventional RISC-V Zicbom extension instructions. This driver provides the
cache handling on StarFive RISC-V SoC.

Changes in v4:
- Move cache controller initialization to arch_initcall()
- Link to v3: https://lore.kernel.org/all/20240424075856.145850-1-joshua.yeong@starfivetech.com/

Changes in v3:
- Fix code syntax
- Link to v2: https://lore.kernel.org/all/20240423072639.143450-1-joshua.yeong@starfivetech.com/

Changes in v2:
- Change patch title from 'Add StarFive's StarLink-500 Cache Controller'
- Remove StarFive alternative from errata framework
- Fixes warning from https://lore.kernel.org/oe-kbuild-all/202403151625.boKDjHGr-lkp@intel.com/
- Flush completion through atomic timeout function
- Link to v1: https://lore.kernel.org/lkml/20240314061205.26143-1-joshua.yeong@starfivetech.com/
