slavio_intctl: avoid structure holes spotted by pahole

Report from pahole on amd64 host:
struct SLAVIO_INTCTLState {
	SysBusDevice               busdev;               /*     0  5648 */

	uint32_t                   intregm_disabled;     /*  5652     4 */
	uint32_t                   target_cpu;           /*  5656     4 */

	/* XXX 4 bytes hole, try to pack */

	qemu_irq                   cpu_irqs[16][16];     /*  5664  2048 */
	/* --- cacheline 120 boundary (7680 bytes) was 32 bytes ago --- */
	SLAVIO_CPUINTCTLState      slaves[16];           /*  7712   384 */

	/* XXX 4 bytes hole, try to pack */

	struct SLAVIO_INTCTLState * master;              /*     8     8 */
	uint32_t                   cpu;                  /*    16     4 */

};	/* definitions: 1 */

Fix by rearranging the structures to avoid padding.
