xen/dom0less: pass kernel_info struct instead of fdt to make_cpus_node()

There are two reasons of this change:
1. Align prototype with what other make_*_node() are passed.
2. A follow-up RISC-V patch will call get_next_free_phandle() inside
   make_cpus_node(), requiring mutable access to kinfo->free_phandle.
