I would suggest to try to boot on usb as root fs for a try.
Also it could be useful to compare the device tree on xen and without xen to
understand what is going on (using /proc/device-tree).
Xen seems to be ok but Linux is not happy with interrupts and is showing
several issues around this area on your logs.
Could you show us an extract of your device tree around the gic declaration ?
