With the new device tree structure, the interrupt field needs to be part
of the vf500.dtsi now. The vfxxx.dtsi will be the parent also for the
Cortex-M4 device tree, which uses a different interrupt controller.
While at it, use the GIC_SPI macro for the first cell (so this will be
blend into the other interrupt definitions).
