x86_dtb_parse_smp_config() must be set by DeviceTree platform for parsing SMP configuration. Set the parse_smp_cfg pointer to x86_dtb_parse_smp_config() by default so that all the dtb platforms need not to assign it explicitly. Today there are only two platforms using DeviceTree in x86, ce4100 and hv_vtl. Remove the explicit assignment of x86_dtb_parse_smp_config() function from these.
