doc,xen: document hypervisor sysfs nodes for xen
Today only a few sysfs nodes under /sys/hypervisor/ are documented for Xen in Documentation/ABI/testing/sysfs-hypervisor-pmu. Add the remaining Xen sysfs nodes under /sys/hypervisor/ in a new file Documentation/ABI/stable/sysfs-hypervisor-xen and add the Xen specific sysfs docs to the MAINTAINERS file.
