This function, being a variant of walk_system_ram_res() introduced in
commit 8c86e70ace ("resource: provide new functions to walk through
resources"), walks through a list of all the resources of System RAM in
reversed order, i.e., from higher to lower.
It will be used in kexec_file code to load kernel, initrd etc when
preparing kexec reboot.
