powerpc, kexec_file: factor out memblock-based arch_kexec_walk_mem()
Memblock list is another source for usable system memory layout. So move powerpc's arch_kexec_walk_mem() to common code so that other memblock-based architectures, particularly arm64, can also utilise it. A moved function is now renamed to kexec_walk_memblock() and integrated into kexec_locate_mem_hole(), which will now be usable for all architectures with no need for overriding arch_kexec_walk_mem(). With this change, arch_kexec_walk_mem() need no longer be a weak function, and was now renamed to kexec_walk_resources(). Since powerpc doesn't support kdump in its kexec_file_load(), the current kexec_walk_memblock() won't work for kdump either in this form, this will be fixed in the next patch.
