add wait_sync_change and arch_get_pcpu_num implementation for riscv. MAX_PCPU_NUM comes from board_info.h generated by config tool. v2->v3: remove riscv cpu.c include asm/cpu.h v1->v2: implement arch_get_num_available_cpus(); Tracked-On: #8801 signed-off-by: Haicheng Li <haicheng.li@intel.com> Co-developed-by: hangliu1 <hang1.liu@intel.com> Signed-off-by: hangliu1 <hang1.liu@intel.com> Reviewed-by: Wang, Yu1 <yu1.wang@intel.com> Reviewed-by: Liu, Yifan1 <yifan1.liu@intel.com> Acked-by: Wang, Yu1 <yu1.wang@intel.com>
