riscv: Rename "sp_in_global" to "current_stack_pointer"
To follow the existing per-arch conventions, rename "sp_in_global" to "current_stack_pointer". This will let it be used in non-arch places (like HARDENED_USERCOPY). Signed-off-by: Kees Cook <keescook@chromium.org> Signed-off-by: Palmer Dabbelt <palmer@rivosinc.com>
