cpuidle: riscv: support non-SMP config

Browse source 
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]
