Subject: [PATCH v2] riscv: mm: init: make pt_ops_set_[early|late|fixmap] static

These three functions are only used in init.c, so make them static.
Fix W=1 warnings like below:

arch/riscv/mm/init.c:721:13: warning: no previous prototype for function
'pt_ops_set_early' [-Wmissing-prototypes]
   void __init pt_ops_set_early(void)
               ^

Signed-off-by: Jisheng Zhang <jszhang@...nel.org>
Reviewed-by: Anup Patel <anup@...infault.org>
---

since v1:
 - collect Reviewed-by tag
 - move out from the static key series as a separate patch
