xen/arm: Add some useful debug in coprocessor trapping

XSA-93 adds a couple of new functions to trap coprocessor registers. They
unconditionally inject an undefined instruction to guest.

When debugging an OS at early stage, it may be hard to know why the guest
received an UNDEFINED. Add some debug message to help the developer when Xen
is built in debug mode.
