Add <asm/smp.h> for cpuid_to_hartid_map etc.
This is needed for both SMP and non-SMP builds, but not having it
causes a build error for non-SMP:

drivers/cpuidle/cpuidle-riscv-sbi.c: In function 'sbi_cpuidle_init_cpu':
drivers/cpuidle/cpuidle-riscv-sbi.c:350:26: error: implicit declaration of function 'cpuid_to_hartid_map' [-Werror=implicit-function-declaration]

I suggest include linux/smp.h here instead of asm/smp.h

Otherwise it looks good to me.

Yeah, checkpatch also suggested that but it does not work.
Yes, I tested it.

linux/smp.h only #includes <asm/smp.h> if CONFIG_SMP is enabled,
and this patch needs <asm/smp.h> for the non-SMP case.
