[PATCH] include: Fix LLVM compile error in sbi_utils/hsm/fdt_hsm_sifive_inst.h

[Anup Patel]

Currently, OpenSBI fails to compile for LLVM=1 using 2025.11.27
riscv-gnu-toolchain with the following error:

      |               ^
2 errors generated.

To fix this compile error, use ".word" in-place ".insn".
