util: Add functions for s390x mmio read/write
Starting with z15 (or newer) we can execute mmio instructions from userspace. On older platforms where we don't have these instructions available we can fallback to using system calls to access the PCI mapped resources. This patch adds helper functions for mmio reads and writes for s390x.
