Subject: [PATCH v2 2/7] riscv: traps: remove __visible annotation

Commit f307307992bf ("riscv: for C functions called only from assembly,
mark with __visible") resolve sparse warnings for C functions called
only by assembly code by adding __visible annotations instead of
adding prototypes. But after commit 030f1dfa8550 ("riscv: traps: Fix no
prototype warnings"), prototypes were added. So the __visible
annotations are not needed any more, remove them.
