[PATCH 07/15] xen: arm: stub out wallclock time.

[Ian Campbell <ian.campbell@citrix.com>]

We don't currently have much concept of wallclock time on ARM (for
either the hypervisor, dom0 or guests). For now just stub everything
out. Specifically domain_set_time_offset, update_vcpu_system_time and
wallclock_time.
