RISC-V: Fix build warning for smpboot.c
The following warnings are reported by kbuild with W=1.
>> arch/riscv/kernel/smpboot.c:109:5: warning: no previous prototype for
'start_secondary_cpu' [-Wmissing-prototypes]
109 | int start_secondary_cpu(int cpu, struct task_struct *tidle)
| ^~~~~~~~~~~~~~~~~~~
arch/riscv/kernel/smpboot.c:146:34: warning: no previous prototype for
'smp_callin' [-Wmissing-prototypes]
146 | asmlinkage __visible void __init smp_callin(void)
| ^~~~~~~~~~
Fix the warnings by marking the local functions static and adding the prototype
for the global function.
