xen/arm: compile and run xenbus
bind_evtchn_to_irqhandler can legitimately return 0 (irq 0): it is not
an error.
If Linux is running as an HVM domain and is running as Dom0, use
xenstored_local_init to initialize the xenstore page and event channel.
Changes in v4:
- do not xs_reset_watches on dom0.
Changes in v2:
- refactor xenbus_init.
