Subject: [PATCH v1 0/2] riscv: hwprobe: add Zicbop support

Add UAPI and kernel plumbing to expose the Zicbop extension presence
and its block size through sys_hwprobe(). The interface mirrors
Zicbom/Zicboz. This allows userspace to safely discover and optimize
for Zicbop when available.

  riscv: hwprobe: report Zicbop presence and block size
