xen/arm: Initialize correctly IRQ routing

When Xen initialize the GIC distributor, we need to route all the IRQs to
the boot CPU. The CPU ID can differ between Xen and the GIC.

When ITARGETSR0 is read, each field will return a value that corresponds
only to the processor reading the register. So Xen can use the PPI 0 to
initialize correctly the routing.
